Do autotrophs need to carry out cellular respiration? why or why not?

The correct answer will be option- true.

Explanation:

Autotrophs are the organism which can prepare their food on their own like green plants, algae and photosynthetic bacteria.   All these autotrophic organisms have the mechanism to synthesize food using the process photosynthesis but to make energy molecules like ATP the process used is cellular respiration.  

Not all the organs of the plants are able to photosynthesize like roots, stems, fruits. So the energy is produced in these organs from the breakdown of the glucose molecules through glycolysis, Krebs cycle and electron transport chains which are considered a process of the cellular respiration.

Thus, option- true is the correct answer.
