Final answer:
Heterotrophs are organisms that cannot produce their own food and must obtain nutrition from other sources. Autotrophs are organisms that can produce their own food through processes like photosynthesis or chemosynthesis.
Step-by-step explanation:
Heterotrophs are organisms that cannot produce their own food and must obtain nutrition from other sources. They are dependent on consuming other organisms or organic matter to meet their energy needs. Examples of heterotrophs include animals, fungi, and many microorganisms.
In contrast, autotrophs are organisms that can produce their own food through processes like photosynthesis or chemosynthesis. They convert inorganic substances into organic compounds, using sunlight or chemical energy as their primary source of energy. Examples of autotrophs include plants, algae, and some bacteria.
