Q

What is cellular respiration and photosynthesis, how are they connected?

A

Cellular respiration is the process in which an organism uses oxygen to break down molecules, and photosynthesis is the conversion of solar energy to chemical energy. They are connected because they are the opposite progresses that compliments each other.
