What process breaks glucose down to be used as an energy source?

Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP.

1. Glycolysis

The initial breakdown of glucose occurs in the cell cytoplasm. This is an anaerobic reaction of cellular respiration, meaning that it does not require oxygen. Here, in a series of eight individual reactions, a six-carbon glucose molecule is metabolized using two adenosine triphosphate (ATP) molecules to form two three-carbon pyruvate molecules, two H.

Explanation:

really dont know just need some points

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
