Final answer:
Autotrophs are organisms that can produce their own food using light or inorganic compounds as a source of energy. Grasses are an example of autotrophs, while hawks, frogs, and rabbits are heterotrophs that rely on consuming other organisms for energy.
Step-by-step explanation:
An autotroph is an organism that can produce its own food using light (photosynthesis) or inorganic compounds (chemosynthesis) as a source of energy. Grasses are examples of autotrophs, as they use photosynthesis to convert sunlight into energy. Hawks, frogs, and rabbits are examples of heterotrophs, which rely on consuming other organisms for their energy and nutrients.
