Detailed explanation-1: -cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

Detailed explanation-2: -Cellular respiration is a process that occurs in the mitochondria of all organisms. In this process, both plants and animals break down simple sugars into carbon dioxide and water and release energy in the form of adenosine triphosphate (ATP).

Detailed explanation-3: -Complete answer: 2)The reason why cellular respiration occurs is the need for energy in both plants and animals. The only difference is that plants undergo photosynthesis and can obtain their energy through solar energy but animals cannot undergo photosynthesis so they are dependent on plants for obtaining energy.

Detailed explanation-4: -Cellular respiration takes place in the cells of animals, plants, and fungi, and also in algae and other protists. It is often called aerobic respiration because the process requires oxygen (the root aer comes from the Greek word for “air”).

Detailed explanation-5: -Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body. There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.
