An organism can "make a living" and survive in its niche.
The correct answer is C, Oxygen.
During aerobic cellular respiration, oxygen combines with hydrogen ions and water is released as a by-product of respiration.
Explanation;
Cellular respiration allows organisms to release energy stored in chemical bonds of glucose, and other nutrients. The energy in glucose or other nutrients such as fats is used to produce ATP, which cells use to supply their energy needs. During aerobic respiration (in presence of oxygen), oxygen is reduced and water is produced together with carbon dioxide as by-products.
Answer:
A small amount of fat is an essential part of a healthy, balanced diet. Fat is a source of essential fatty acids, which the body cannot make itself. Fat helps the body absorb vitamin A, vitamin D and vitamin E. These vitamins are fat-soluble, which means they can only be absorbed with the help of fats.
Explanation: Blah blah blah
It's B because during day when temperature of air is increased water retains most of the heat to keep the temperature of atmosphere at tolarable limit. During night when sun sets ocean transfer its heat to atmosphere as heat always transfer from region of high temperature to region of low temperature. In this way temperature of air is stabilized.
Hope it makes sense to you
