Michael is giving a presentation on the ecological pyramid of numbers. Help him complete the sentences. In the pyramid of numbers generally, the are the highest in number. Therefore, they occupy the base of the pyramid. The subsequent trophic levels where the numbers of organisms decrease occupy the upper levels. However, pyramid of numbers does not prove useful in most of the cases. Scientists have to the number of organisms in each trophic level, which is a difficult task.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
