Organic compounds produced outside themselves.
Performed organic compounds
Bacteria may also be classified both by the mode by which they obtain their energy. Classified by the source of their energy, bacteria fall into two categories: heterotrophs and autotrophs. Heterotrophs derive energy from breaking down complex organic compounds that they must take in from the environment -- this includes saprobic bacteria found in decaying material, as well as those that rely on fermentation or respiration.
Autotrophs
Humans are not free-living organisms as they parasitically derive nutrition from the suffering of others.
Actually they are not autotrophs,they are phototrophs.Autotrophs are organisms who use CO2 as Carbon sourse.
Autotrophs are living beings that are able to derive energy from a source other than another living being- the source being sunlight or chemicals in the environment. Autotrophs include but are not limited to; plants who photosynthesize sunlight into chemical energy and microorganisms that live off of the chemicals secreted by hydrothermal vents deep under the ocean. With that being said, many things eat autotrophs- as a matter of fact most food systems start with auotrophs at the bottom. Some animals that eat autotrophs - Humans, dogs, hummingbirds, cows and horses. These animals are more largely called heterotrophs because they cannot derive their metabolic energy on their own- they must consume it through their diet by eating plants if they are herbivorous or meat if they are carnivorous.
Heterotrophs. These organisms derive their food from autotrophs,that is, the plants. They include- Carnivores, herbivores, omnivores, scavengers, decomposers.
Autotrophs
Basically, there are two types of organisms: AUTOTROPHS & HETEROTROPHS. Autotrophs: These basically consist of the plants.They derive their energy from the sun by a system called photosynthesis. This energy helps provide them with what is required to survive. Heterotrophs: These are the animals that feed on themselves as well as on plants. They derive their energy from the plants. They get a lower level of energy at each stage of consumption.

No, vegetarians, or better described, as herbivores in this example, are not the only heterotrophs that get all their energy from plants. All living organisms, including carnivores, also derive energy from plants by eating the herbivores.

Organic molecules form the structure of all living organisms and derive energy from the organism's environment.
