Which statement best describes photosynthesis and respiration?

Responses

Autotrophs carry out photosynthesis, while autotrophs and heterotrophs carry out respiration.
Autotrophs carry out photosynthesis, while autotrophs and heterotrophs carry out respiration.

In autotrophs, photosynthesis requires oxygen, and respiration requires carbon dioxide.

The statement that best describes photosynthesis and respiration is:

Autotrophs carry out photosynthesis, while autotrophs and heterotrophs carry out respiration.

This is accurate because autotrophs (like plants) perform photosynthesis to convert light energy into chemical energy, while both autotrophs and heterotrophs (organisms that consume other organisms for energy) carry out respiration to release energy from the organic compounds.
