Final answer:
Autotrophs are organisms that can produce their own food through processes like photosynthesis and chemosynthesis. They are the primary producers in an ecosystem, providing energy for other organisms.
Step-by-step explanation:
Autotrophs are organisms that manufacture their own food. They are able to produce organic compounds such as glucose through the process of photosynthesis or chemosynthesis. Examples of autotrophs include plants, algae, and certain bacteria.
