9. In one or two sentences, describe how the available energy may affect the population sizes of organisms at different trophic levels

Explanation:

In food web energy are been transfered from the producer which are often plants down to the last individual on the web.

Each individual takes in and expels the remaining to the next until it is distributed to all. The amount of energy received from the producer will determine the amount of energy that will be available for others to share, when enough energy is transferred they all have enough to share but when the energy level is low the individual on the web also receive a low energy this may affect the population leading to a reduction,

It can also lead to competition among the organisms,migration out of environment to search for food. But When the energy level is high or on the increase it leads to growth and development among the organism.
