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

Autotrophs and heterotrophs both carry out photosynthesis and then respiration.
Autotrophs and heterotrophs both carry out photosynthesis and then respiration.

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

Only autotrophs carry out photosynthesis, while only heterotrophs carry out respiration.

The statement that best describes photosynthesis and respiration is:

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

This correctly identifies that autotrophs, such as plants, perform photosynthesis to create their own food using sunlight, while both autotrophs and heterotrophs (organisms that consume other organisms for energy) perform respiration to convert glucose and oxygen into energy, carbon dioxide, and water.
