What is energy flow in the food chain?
Energy Flow. The chemical energy of food is the main source of energy required by all living organisms. This energy is transmitted to different trophic levels along the food chain. This energy flow is based on two different laws of thermodynamics: First law of thermodynamics, that states that energy can neither be created nor destroyed, ...
What is meant by food chain?
Food chain - It is the chain of an organism through which energy is transferred in the form of food by the process of one organism consuming another. (i) The energy captured by autotrophs (plants) does not revert back to the solar input (sun).
What is the first stage of the food chain?
1 The Sun: The sun is the initial source of energy, which provides energy for everything on the planet. 2 Producers: The producers in a food chain include all green plants. This is the first stage in a food chain. ... 3 Consumers: Consumers are all organisms that are dependent on plants or other organisms for food. ...
What are the levels of a food chain?
Every level in a food chain is known as a trophic level. The food chain consists of four major parts, namely: The Sun: The sun is the initial source of energy, which provides energy for everything on the planet. Producers: The producers in a food chain include all green plants. This is the first stage in a food chain.

What are the 4 steps of the food chain?
The four levels in this food chain are primary consumers, secondary consumers, tertiary consumers, and finally decomposers or phytoremediators.
What is the flow of energy in a food chain?
A food chain shows how energy flows from one organism to another. In general, energy flows from the Sun to producers and then to consumers. The path is linear as the energy present in one step is transferred to the next. You can find specific examples of this pathway in an ecosystem.
How do you explain a food chain to a child?
Some animals eat plants and some animals eat other animals. For example, a simple food chain links the trees & shrubs, the giraffes (that eat trees & shrubs), and the lions (that eat the giraffes). Each link in this chain is food for the next link. A food chain always starts with plant life and ends with an animal.
What is the direction of flow of energy in a food chain Class 10?
The energy stored in the plants through photosynthesis is transferred to herbivores that feed on the plants. From herbivores, energy is transferred to carnivores that feed on them. So the direction of the flow of energy is from the sun to the carnivores.
What is the food chain?
Food Chain: Introduction. A food chain explains which organism eats another organism in the environment. The food chain is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other. This occurs when one organism consumes another organism. It begins with producer organism, ...
What are the main parts of the food chain?
The food chain consists of four major parts, namely: 1 The Sun: The sun is the initial source of energy, which provides energy for everything on the planet. 2 Producers: The producers in a food chain include all autotrophs such as phytoplankton, cyanobacteria, algae, green plants. This is the first stage in a food chain. The producers make up the first level of a food chain. The producers utilise the energy from the sun to make food. Producers are also known as autotrophs as they make their own food. Producers are any plant or other organisms that produce their own nutrients through photosynthesis. For example, green plants, phytoplankton and algae are some examples of producers in a food chain. 3 Consumers: Consumers are all organisms that are dependent on plants or other organisms for food. This is the largest part of a food web, as it contains almost all living organisms. It includes herbivores which are animals that eat plants, carnivores which are animals that eat other animals, parasites are those organisms that live on other organisms by harming them and lastly the scavengers, which are animals that eat dead animals’ carcasses.
What happens when one organism consumes another organism?
This occurs when one organism consumes another organism. It begins with producer organism, follows the chain and ends with decomposer organism. After understanding the food chain, we realise how one organism is dependent upon another species for survival.
How do decomposers help the food chain?
Decomposers complete a life cycle. They help in recycling the nutrients as they provide nutrients to soil or oceans, that can be utilised by autotrophs or producers. Thus, starting a whole new food chain.
What is the food chain that starts with green plants, passes through herbivores and then to carni?
Grazing food chain: The grazing food chain is a type of food chain that starts with green plants, passes through herbivores and then to carnivores. In a grazing food chain , energy in the lowest trophic level is acquired from photosynthesis. In this type of food chain, the first energy transfer is from plants to herbivores.
What is the order of events in an ecosystem?
A food chain refers to the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism. The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain.
How are food webs connected?
But a food web shows different paths, where plants and animals are connected. A food web comprises several food chains. In a food chain, an organism eats a single item, whereas in a food web an organism consumes multiple items. In a food chain, there is a singular path for energy flow and in a food web, there are different paths for energy flow.
What is the food chain?
Regarded as the chronological pathway, the food chain is a linear arrangement or series of organisms that are capable of eating one another so that the essential nutrients and energy flow from one living organism to the next one.
What is the food chain in a terrestrial ecosystem?
The foremost source of energy is the sun and plants or producers use sunlight to make their food through the process of Photosynthesis. The next element in this chain is the animal or consumer whose food is the plant at the previous level .
What is the detritus food chain?
Detritus Food Chain: The detritus food chain includes dead organic matter. It includes species of organisms and plants like algae, bacteria, fungi, protozoa, mites, insects, worms, and so on. In this food chain, the dead organic matter of plants and animals is broken down by decomposers and detritivores that are further eaten by smaller organisms ...
What are phytoplankton eaten by?
For example, phytoplanktons are eaten by zooplanktons, zooplanktons are eaten by fishes and small fishes by large fishes.
What are trophic levels in food chain?
The trophic levels of the food chain can be easily understood as: As per the trophic levels, here is an example: Often we encounter animals consuming dead and decaying matter, such chains that begin with the consumer eating dead organic matter are known as Detritus Food Chain (DFC).
What is the process of making food in the aquatic system?
Autotrophs: They are the ones who can make their own food from inorganic sources. The process is usually done by Photosynthesis. Photosynthesis in the aquatic system begins from wide variety of autotrophs or producers which ranges from microscopic single-celled organisms to large aquatic plants.
What is a consumer in the food chain?
A consumer in a food chain is a living creature that eats organisms from a different population. A consumer is also called a heterotroph. Consumers are usually predatory animals such as meat-eaters but also the herbivorous consumers that eat plants. For example, a tiger and a deer are both consumers.
Love is the way we live with each other
When we talk about what love is, among the many aspects and depths of love that cannot be described in a single word, I would venture to say that one of them is the way we live with each other.
Every living being is kept alive by other lives
If we trace it further back, it is the sun’s energy that keeps the plants alive. It takes the sun’s energy and converts it into another form of energy that keeps other living things alive.
The fires are coming down on the people themselves, who are out of balance with the natural world
If we do things that are selfish and selfish because of our ego, the result will be that we will have to pay the consequences back in a big way. The sparks will fall on those who have lost the balance of harmony.
What is the energy flow of food?
Energy Flow. The chemical energy of food is the main source of energy required by all living organisms. This energy is transmitted to different trophic levels along the food chain. This energy flow is based on two different laws of thermodynamics: First law of thermodynamics, that states that energy can neither be created nor destroyed, ...
What are the different types of food chains?
Food Chain. There are basically three different types of food chains in the ecosystem, namely –. Grazing food chain (GFC) – This is the normal food chain that we observe in which plants are the producers and the energy flows from the producers to the herbivores (primary consumers), then to carnivores (secondary consumers) and so on.
What is the trophic level of an ecosystem?
Trophic level. The producers and consumers in the ecosystem can be arranged into different feeding groups and are known as trophic level or the feeding level . The producers (plants) represent the first trophic level. Herbivores (primary consumers) present the second trophic level. Primary carnivores (secondary consumers) represent ...
Why do we observe the food web?
In nature, we mostly observe food web as there are many organisms which are omnivores. As a result, they occupy multiple trophic levels.
When herbivores are ingested by carnivores of the first order (second?
When these herbivores are ingested by carnivores of the first order (secondary consumers ) further degradation will occur. Finally, when tertiary consumers consume the carnivores, energy will again be degraded. Thus, the energy flow is unidirectional in nature. Moreover, in a food chain, the energy flow follows the 10 percent law.
What percentage of the energy is used by plants for photosynthesis?
Overall, we receive about 40 to 50 percent of the energy having Photosynthetically Active Radiation and only around 2-10 percent of it is used by plants for the process of photosynthesis.
How does photosynthesis produce energy?
During the process of energy flow in the ecosystem, plants being the producers absorb sunlight with the help of the chloroplasts and a part of it is transformed into chemical energy in the process of photosynthesis. This energy is stored in various organic products in the plants and passed on to the primary consumers in the food chain when ...
What is the food chain?
Food chain is the single path as animal eat each other where as food web is the how plants and animals are interconnected by different paths. example for food chain is grasshopper eaten by frog.
How does the food chain get its energy?
For ALL food chains (with a few very niche-ey exceptions), energy begins with photosynthesis. If you’re a plant, of course, you’re obtaining your own energy directly via photosynthesis (i.e., the process whereby plant cells use energy from sunlight to synthesize sugars, using carbon dioxide from the air as the starting material). If you’re an animal, whether an elephant or a man or a dolphin or a lizard or a microscopic single-cell organism, you eat something that ate something else that ate something else (etc.), down the food chain until the last item in the chain is something that created its own energy via photosynthesis. Many humans get much of our energy from meat, which more often than not comes from critters such as cows that get their energy from grass and other plants. Pretty short food chain, that. Large carnivorous fish tend to eat smaller fish, that eat smaller fish, etc., etc., the last item in the food chain typically being something like a single-celled or multi-celled alga that got its energy from sunlight via photosynthesis.
How is energy passed through the food chain?
Energy is passed between organisms through the food chain. Food chains start with producers. They are eaten by primary consumers which are in turn eaten by secondary consumers. ... This energy can then be passed from one organism to another in the food chain. the answer is Yes and the control is seldom chequed Michael
How does energy flow in an ecosystem?
Energy flow in an ecosystem starts at the sun which produces all the energy needed for life. Then comes the producers, the autotrophs. These organisms harness the energy of the sun and convert it into sugars. These organisms obtain 100% of the energy they produce. The primary consumers which eat the autotrophs get the next most energy, but this is only 10% of the original energy that the autotrophs got. Next, the secondary consumers, which eat the primary consumers get nutrients, but this is only 1% of the energy that was originally in the plant. Tertiary consumers, at the top of the food chain eat secondary and primary consumers, and they only get 0.1% of the energy.
How much energy does an organism get from the previous level?
Every level of the energy pyramid, those organisms only get 10% of the energy from the previous level.
Where are omnivores present in the food chain?
Omnivores (present on autotrophs as well as heterotrophs) are present at the top of the food chain.
What is the food web?
Well, a food web is a group of interlinked food chains, which means that some grazing food chains are branched together. Before answering your question, let me explain to you how energy flows among living beings.
