What is an autotroph?
Encyclopedic Entry. Vocabulary. An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producer s. Plant s are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.
What do autotrophs use to make energy?
In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy. Plants also use glucose to make cellulose, a substance they use to grow and build cell wall s.
What is the function of autotrophic bacteria?
The autotrophic bacteria oxidize these chemicals to produce energy. Autotrophs in the Food Chain. To explain a food chain —a description of which organisms eat which other organisms in the wild—scientists group organisms into trophic, or nutritional, levels. There are three trophic level s.
What is the food chain in a hydrothermal vent?
In hydrothermal vents, the food chain’s producer is autotrophic bacteria. Primary consumers such as snail s and mussel s consume the autotrophs. Carnivores such as octopus consume the snails and mussels. An increase in the number of autotrophs will usually lead to an increase in the number of animals that eat them.
How do autotrophs make food?
Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen.
Which trophic level is the first?
Because autotrophs do not consume other organisms, they are the first trophic level. Autotrophs are eaten by herbivore s, organisms that consume plants. Herbivores are the second trophic level. Carnivore s, creatures that eat meat, and omnivore s, creatures that eat all types of organisms, are the third trophic level.
Why are some bacteria not autotrophs?

What are some examples of autotrophs?
Examples of Autotroph: 1. Green plants and algae: These are examples of photoautotrophs using light as an energy source. In this type, electromagnetic energy is converted from sunlight into chemical energy in the form of reduced carbon. Green plants and algae are fundamental to the food chains of all ecosystems in the world.
What is an autotroph?
Autotroph Examples. Autotroph. An autotroph is an organism identified as a producer on the primary level of a food chain. Only about 5% of all living organisms are autotrophs. They are often referred to as self-feeders. In fact, the Greek origin of the term autos and trophe can be translated as "self-nourishing".
What are the sources of energy for chemoautotrophs?
The chemoautotrophs use electron donors from organic or inorganic sources as a source of energy. The electron donors come from inorganic chemical sources such as hydrogen sulfide, elemental sulfur, ammonium and ferrous iron. In the food chain, autotrophs are consumed by heterotrophs.
How does the autotroph produce energy?
It will produce these from substances present in the autotroph's surroundings using the process of photosynthesis, obtaining energy from light; or through chemosynthesis, using energy from inorganic chemical reactions.
Do autotrophs need carbon?
The chemical reactions are usually between hydrogen sulfide/methane with oxygen. Autotrophs do not need organic carbon or a living energy source survive. They are known to reduce carbon dioxide to make organic compounds for biosynthesis. In addition, autotrophs can store chemical energy.
Do autotrophs use water?

What is an Autotroph?
Autotrophs are organisms that produce their own food, rather than ingesting other organisms as a source of nutrition. These organisms can come in various sizes and shapes. For example, plants are autotrophs, as they use photosynthesis to convert water and carbon dioxide into sugar.
Types of Autotrophs
There are two main types of heterotrophs: photoautotrophs and chemoautotrophs
Examples of Autotrophs
Examples of Autotrophs Autotrophs are organisms that can photosynthesize. Plants are the two types of autotrophs, the ones most commonly seen by the average person. The other type of plant autotroph is algae. Algae are types of autotrophs that make use of chlorophyll and sunlight to make food.
Autotrophic Plants
Plants are the largest group of autotrophs. They use energy from sunlight to make sugars from carbon dioxide and water. Plants can be found in every part of the world and on all continents except Antarctica. As a result, they may be the first life that any traveler will see.
Heterotrophs
Heterotrophs are organisms that cannot make their own food, and therefore must rely on other organisms for energy. There are many types of heterotrophs in the animal kingdom. Fungi, some types of bacteria, and worms are all examples of heterotrophs.
Examples of Heterotrophs
A heterotroph, or “consumer,” is an organism that cannot fix carbon from inorganic material. A heterotroph either feeds on organic molecules and/or other organisms for its carbon and energy needs, or lives off the photosynthetic fixation of plants.
