Question

how are chemoautotrophs different from photoautotrophs?
they are not different, they both use the sun for their energy.
chemoautotrophs use the breakdown of inorganic molecules to release the energy they need to create their organic substances, not sunlight.
chemoautotrophs use light from the deep sea vents to power photosynthesis.

Explanation:

Chemoautotrophs obtain energy from the breakdown of inorganic molecules (e.g., hydrogen sulfide, ammonia) through chemosynthesis. Photoautotrophs use sunlight for photosynthesis. The first option is incorrect as they are different. The third option is wrong because chemoautotrophs do not use light (from deep - sea vents or elsewhere) for photosynthesis; they use chemical energy. The second option correctly describes the difference.

Answer:

Chemoautotrophs use the breakdown of inorganic molecules to release the energy they need to create their organic substances, NOT sunlight.
