The ecosystem requires a constant input of energy because energy cannot be stored. The enrgy always gets converted for supporting life in the ecosystem. Some amount of energy is also lost during this conversion. So if there is not a constant supply of energy, then the ecosystem will ultimately breakdown. In case of humans, the energy is received by consuming food. The energy of the food geets converted to the enrgy that helps a human being to complete his daily chores. So energy is being lost at every step. To regain this energy the humans have to eat food regularly. This way the humans need a constant supply of energy to survive. It is the same in the case of all living things in the ecosystem.
Answer:
<em>The population of the impala antelopes will decline rapidly.</em>
Explanation:
The cheetahs and leopards are the predators of the impala antelopes. If the population of the predators arises, this means there will be more predators feeding on the prey. As a result, the population of the prey will decline. Hence, in the above scenario, the population of the impala antelopes will decline rapidly as it will have more number of predators. The population of the cheetahs might also start to decline if it does not move on to another source of food.
It will have to be c and d
Radon diffuses out of the earth in small, variable quantities all the time, but this can increase when reductions in pressure allows radon or fluids carrying I. Solution to escape to the surface, such pressure drops can accompany or precede the sharing of rocks in an earthquake!
I believe the answer is c
