How does aerobic respiration relate to plants, animals and humans?
Aerobic respiration occurs in living organisms that require energy to perform various roles(e.g muscle contraction). Aerobic respiration uses oxygen and glucose to produce carbon dioxide water and also energy.
This can be summarised as the word equation
Oxygen + Glucose --> carbon dioxide + water + (energy)
All three, plants animals and humans us respiration to supply energy the need for various tasks.
Hope this helps.
