Question

which factor would have the greatest effect on the cellular respiration rate of an animal?
o the intensity of sunlight
o the number of chloroplasts
o the amount of water available
o the amount of oxygen available

Explanation:

Cellular respiration in animals is an aerobic process that uses oxygen to produce energy. Sunlight affects photosynthesis in plants, not animal cellular respiration. Chloroplasts are present in plant cells for photosynthesis, not relevant to animal cellular - respiration. Water is important for life processes but oxygen is the key reactant for aerobic cellular respiration in animals.

Answer:

the amount of oxygen available
