For giving you understanding ; we need Free O2 but Oxygen is also available in H20 right why dont we use it !!
As the early atmosphere was reducing as there was no free oxygen but it was later produced by chemoautotrophic bacteria !! Living thing release O2 in atmosphere thus making it oxidising in nature and then life evolves !!
Answer:
1. Evaporation
2. Lengthening of a river upslope.
3. Sand and gravel
4. Storm surge
5. Adds clean water to the drinking water supply

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
Hope this helps

You are correct the answer is B. Good luck and good job
Cellular respiration is the metabolic reaction inside the cell to convert chemical energy into ATP. Biomass is the total mass of organisms at a trophic level.
<h3>What is exothermic reaction?</h3>
The type of reaction in which releases energy after its completion.
- Cellular respiration releases energy because it is an exothermic process in which energy is released as a by-product of the reaction.
- Organisms are larger in size at higher trophic levels, but their smaller numbers result in less biomass.
Thus, being exothermic in nature, cellular respiration releases energy and because of less numbers, there is less biomass at high trophic levels.
