Final answer:
Autotrophs are organisms that do not need to consume another organism for food.
Step-by-step explanation:
Omnivores are organisms that consume both plants and animals for food. Autotrophs, on the other hand, are organisms that can produce their own food through processes like photosynthesis. Examples of autotrophs include plants and some types of bacteria. They can use energy from sunlight to convert carbon dioxide and water into glucose, which they can use as food. Unlike carnivores, which only consume other animals, and decomposers, which obtain nutrients from breaking down dead organic matter, autotrophs do not need to consume another organism for food.
