Question
________________transform light energy into chemical energy through a process called photosynthesis, which is then used to energize cellular processes.
- Heterotrophs
- Phototrophs
- Chemotrophs
- None of these
Hint:
Phototrophs can make their own food
The correct answer is: Phototrophs
- Phototrophs are the organisms that can make their own food.
- They use visible light as the primary source of energy for metabolism
- Green plants and blue green algae are phototrophs. They are able to make their own food by the process of photosynthesis
