Explanation:

Under active condition the readily available source of ATP is needed by the muscle to fulfill the energy requirements.

Phosphocreatinine is a molecule that stores energy and recharges ADP to ATP during muscle contraction. So, hydrolysis of phosphocreatinine is the first  mechanism that is employed.

Since anaerobic glycolysis does not require oxygen.The muscle cells find it convinient mechanism to generate ATP by using up the glucose. Thus , this is the second mechanism which is employed.

Glycolysis is the last mechanism employed to generate ATP because this process needs a complete supply of oxygen. Which depends on the availability and diffusion rate of oxygen into the tissues.

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
