The answer is D as there are fluctuations which means that changes in the population of one affects the population of the other. as prey pop increases predator pop increases leading to a decease in prey pop which causes predator pop to decrease due to lack of food then prey increases and the cycle repeats
What I think will happen as time goes by and right this second is that the earth is just going to fill and fill and fill with pollution
B): Energy is radiated more than absorbed near the poles
D): Energy is absorbed more than radiated near the equator.
E): Energy is carried from the equator to poles in surface currents.
Explanation:
Thermal energy is a form of energy carried by heat as a result of temperature differences between two places or bodies.
At the equator the sun is overhead and directly bursting energy from space. Areas around the equator have very low albedo because the bulk of radiation is absorbed. The surfaces here are like black bodies.
At the poles, the ice caps and bodies causes the reflection of the bulk of these radiations. Such regions have a very high albedo. Most of the energy here is radiated.
- Warm water in the equator due to absorbed energy are rises to the surface and are carried away to the pole.
- Colder water moved from the pole towards the equator by deep ocean currents.

Answer:
Explanation: Hydropower is the generation of electricity from water through the construction of dams. it is a renewable energy source use over a wide range of environment. Construction of a waters storage project can raise the water level behind a dam from a few feet to several hundred feet by prevention water free flow called Inundation.
It leads to migration of human and other living organism such as fish and salmon. Salmon movement may be disoriented through the slower move of the water this leads to migration.
Fish moving around the dam coming in contact with turbines and the walls of the dam can become stressed, injured or die
vegetation and surrounding water it provide habitat for birds, waterfowl, and small and large mammals when hydroelectric project results in blockage of free-flowing river, the nesting, forage, and cover provided for the organism in these areas is temporarily or permanently lost.
