This is the process that releases energy by breaking down food molecules in the precence of oxygen

CELLULAR RESPIRATION

Explanation:

Cellular respiration is defined as the oxidation (break down in the presence of oxygen) of organic food substances within the cell leading to the release of energy, carbon dioxide and water.

It can be represented by the equation:

C6H12O6 + 6O2 --> 6H2O + 6CO2 + Energy (in form of ATP)

Thus, the main purpose of cellular respiration that takes place in a cell is to generate energy required by the whole body.

explanation:

the panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in earth's temperatures over the past 50 years.
