Explain how autotrophs need both cellular respiration and photosynthesis

They get energy from food. Autotrophs make their own food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose. And as for cellular respiration, all organisms use it to break down glucose, release its energy, and make ATP.

Explanation:

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.

c.more precipitation,but only when emission levels.
