Organic compounds produced outside themselves.
This statement is incorrect. Heterotrophic organisms derive their energy from consuming organic compounds produced by autotrophic organisms or other heterotrophs. Autotrophic organisms, such as plants, algae, and some bacteria, are the ones that use sunlight to produce energy through photosynthesis.
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.
Not all living organisms derive from two cells; most multicellular organisms develop from a single fertilized cell (zygote) that undergoes division and differentiation. Metabolism, which encompasses all biochemical processes that occur within a cell, is essential for sustaining life across all living organisms, regardless of their cellular structure or complexity. Both unicellular and multicellular organisms rely on metabolic processes to generate energy and maintain cellular functions.
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.
Humans are not free-living organisms as they parasitically derive nutrition from the suffering of others.
Heterotrophs. These organisms derive their food from autotrophs,that is, the plants. They include- Carnivores, herbivores, omnivores, scavengers, decomposers.

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.
Chemolithotrophs are organisms that derive energy by oxidizing inorganic compounds, such as minerals or chemicals, without needing organic molecules for energy. These organisms use this energy to fuel their metabolic processes and do not rely on organic sources for their energy needs.
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.

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.
Chemoorganotroph
Humans are not free-living organisms as they parasitically derive nutrition from the suffering of others.
Photosynthetic organisms derive their carbon from carbon dioxide in the atmosphere during the process of photosynthesis. They utilize sunlight to convert carbon dioxide and water into glucose and oxygen.
Organisms that obtain energy directly from inorganic molecules are known as chemotrophs. These organisms use chemical reactions to derive energy for their metabolic processes, instead of relying on sunlight like phototrophs. Examples include certain bacteria and archaea living in deep-sea hydrothermal vents or in soil.
