Answer:
B. The equator is susceptible to extreme storms so the thermocline changes significantly throughout the year.
Explanation:
Storms occurs on that locations where there is high temperature and high temperature is only present at the equator due to direct sunlight. So we can say that maximum storms comes at and near the regions of equator. The oceans present near the equator have a warm layer known as thermocline from where water is evaporated and the intensity of storms are also increases.
B) population because there is more than one in one species and types

During the process of nitrogen fixation, nitrogen is absorbed from the atmosphere and it is fixed by nitrogen fixing organisms.
