Final answer:
Autotrophs can produce their own food through photosynthesis or chemosynthesis. Algae, trees, and flowers are examples. Bears cannot produce their own food.
Step-by-step explanation:
Autotrophs are organisms that can produce their own food using energy from sunlight or inorganic compounds. They are capable of photosynthesis or chemosynthesis. Algae, trees, and flowers are examples of autotrophs because they can produce their own food through photosynthesis. On the other hand, a bear cannot produce its own food and relies on consuming other organisms, so it would not be considered an autotroph.
