How are cellular respiration and photosynthesis related?

Products of photosynthesis are used in cellular respiration

Explanation:

Photosynthesis is a process performed by the plants (also some algae and bacteria) in which the energy of sunlight is transformed into chemical energy usable by those plants. Necessary components of this set of reactions are sunlight, water and CO2, while resulting products are glucose and oxygen. Products of photosynthesis are then used in the metabolic processes known as cellular respiration. During the cellular respiration, glucose and oxygen are used for the production of ATP, CO2 and water. Cellular respiration is performed in mitochondria of all living organisms.

Photosynthesis occur in the chloroplast, membrane organelles with photosynthetic pigments (such as chlorophyll).

the correct answer is:

a population changes in response to a change in the environment.
