What is a trophic level in science? In ecology, the trophic level is the position that an organism occupies in a food chain - what it eats, and what eats it. Wildlife biologists look at a natural "economy of energy" that ultimately rests upon solar energy. Next are carnivores (secondary consumers) that eat the rabbit, such as a bobcat.
What does trophic level mean?
Trophic level, step in a nutritive series, or food chain, of an ecosystem. The organisms of a chain are classified into these levels on the basis of their feeding behaviour. The first and lowest level contains the producers, green plants.
What are examples of trophic level?
What is a Trophic Level? A community is an assemblage of populations organisms living in the same area at the same time. Community ecologists study which species coexist, how they interact, how communities change over time, and why these patterns occur. Some of the most important interactions among community members involve who eats whom.
What is a trophic level?
Trophic Level Definition. A trophic level is the group of organisms within an ecosystem which occupy the same level in a food chain. There are five main trophic levels within a food chain, each of which differs in its nutritional relationship with the primary energy source. The primary energy source in any ecosystem is the Sun (although there are ...
What are the three levels of the trophic system?
Trophic levels three, four and five consist of carnivores and omnivores. Carnivores are animals that survive only by eating other animals, whereas omnivores eat animals and plant material. Trophic level three consists of carnivores and omnivores which eat herbivores; these are the secondary consumers. Trophic level four contains carnivores and ...
What happens to the ecosystem if there are fewer available plant resources?
If there are fewer available plant resources, other organisms that depend on the plants (although are not hunted by the apex predator), such as insects and small mammals, will suffer population declines, and in turn can affect all trophic levels within an ecosystem.
What are some examples of disruption within one of the trophic levels?
However, disruption within one of the trophic levels, for example, the extinction of a predator, or the introduction of a new species, can have a drastic effect on either the lower or higher trophic levels.
What is the term for an organism that gains a portion of its energy intake from the tissues of other animals?
Carnivore – An organism that gains a portion of its energy intake from the tissues of other animals. Herbivore – An organism that obtains its energy solely from plant material. Trophic cascade – The occurrence of a predator suppressing the population size of lower trophic levels.
Do trophic levels have a uniform chain?
It is important to note that organisms within the trophic levels of natural ecosystems do not generally form a uniform chain, and that many animals can have multiple prey and multiple predators; the non-linear interactions of trophic levels can therefore be best viewed as a food web rather than a food chain.
Do decomposers fill trophic levels?
Although they do not fill an independent trophic level, decomposers and detritivores, such as fungi, bacteria, earthworms and flies, recycle waste material from all other trophic levels and are an important part of a functioning ecosystem. Due to the way that energy is utilized as it is transferred between levels, ...

Answer: Trophic Levels: The various steps in a food chain at which the transfer of food (or energy) takes place are called trophic levels. Example: A food chain operating in a grassland is given below: Grass → Insects → Frog → Birds.
What are the six trophic levels?
Primary Producers. Primary producers, or ”autotrophs”, are organisms that produce biomass from inorganic compounds.
What is the highest trophic level?
The highest trophic level is the apex predators. Primary consumers are carnivores that survive on secondary consumers (herbivores).
What are the 3 main trophic levels?
Level 1: Plants and algae make their own food and are called producers. Level 2: Herbivores eat plants and are called primary consumers. Level 3: Carnivores that eat herbivores are called secondary consumers. Level 4: Carnivores that eat other carnivores are called tertiary consumers.
What is a trophic level easy definition?
Trophic level, step in a nutritive series, or food chain, of an ecosystem. The organisms of a chain are classified into these levels on the basis of their feeding behaviour. The first and lowest level contains the producers, green plants.
What is a trophic effect?
Trophic hormones are hormones of the anterior lobe of the pituitary. These hormones affect growth, function, or nutrition of other endocrine cells. The term trophic is from Ancient Greekτροφικός (trophikós) meaning “pertaining to food or nourishment”, here used to mean “growth”; this is the same origin as atrophy.

Top predators, who control populations of lower trophic level consumers, are often keystone species
Top predators, who control populations of lower trophic level consumers, are often keystone species.
What is an example of a trophic level?
The first trophic level is composed of algae and plants. Examples include seaweed, trees, and various plants. The second trophic level is composed of herbivores: animals that eat plants. They are considered primary consumers, since they are the first to eat the producers that make their own food.
What is a trophic level in a food chain?
In ecology, a trophic level pertains to a position in a food chain or ecological pyramid occupied by a group of organisms with similar feeding mode. A food chain refers to the hierarchy in which organisms in an ecosystem are grouped into trophic (nutritional) levels.
What are trophic levels Kids definition?
A food chain describes the order in which organisms eat each other in the wild. The different positions in a food chain are called trophic levels. The amount of energy passed along decreases as it is transferred up trophic levels by about 10% in each level.
What is trophic level in ecosystem?
In ecology, the trophic level is the position that an organism occupies in a food chain – what it eats, and what eats it. Wildlife biologists look at a natural “economy of energy” that ultimately rests upon solar energy. Next are carnivores (secondary consumers) that eat the rabbit, such as a bobcat.
What is called trophic level?
A trophic level is the group of organisms within an ecosystem which occupy the same level in a food chain. The second trophic level consists of herbivores, these organisms gain energy by eating primary producers and are called primary consumers.

Definition. adjective. (1) Of, relating to, or pertaining to nutrition. (2) Of, or involving, the feeding habits or food relationship of different organisms in a food chain.
What is the trophic level of a tree?
Oak trees are primary producers, thus they make up the first trophic level and would be found alongside other primary producers.
What does trophic mean in science?
trophic Add to list Share. Trophic things have something to do with food, eating, or nutrition. You’re most likely to encounter this word in an Earth science or biology textbook, where you might read about trophic webs, or interconnected food chains. Trophic has a Greek root, trophe, “nourishment or food.”

What are the two levels of organisms that eat plants?
The plants or their products are consumed by the second-level organisms—the herbivores, or plant eaters. At the third level, primary carnivores, or meat eaters, eat the herbivores; and at the fourth level, secondary carnivores eat the primary carnivores.
What is the trophic level of an ecosystem?
The trophic level is the position an organism occupies in the food chain. The first trophic level known as the base of the ecosystem has the highest energy concentration which is transferred to the organisms at different trophic levels.
Which trophic level includes all carnivores and omnivores?
These are secondary consumers and derive their nutrition from the primary consumers. Tertiary Consumers: This is the fourth trophic level that includes all the carnivores and omnivores. Apex Predators: This is the final trophic level of the ecosystem.
Trophic Level Definition
Examples of Trophic Level
- Primary Producers
Primary producers, or ”autotrophs”, are organisms that produce biomass from inorganic compounds. In general, these are photosynthesizingorganisms such as plants or algae, which convert energy from the sun, using carbon dioxide and water, into glucose. This glucose is then … - Primary Consumers
Primary consumers are herbivores, that is, animals that are adapted to consuming and digesting plants and algae (autotrophs). Herbivores are generally split into two categories: grazers, such as cows, sheep and rabbits, whose diets consist at least 90% of grass, and browsers, such as deer …
