Which of the following is an example of how a biotic factor can affect the population dynamics in an ecosystem? lack of water during a drought causes many of the individuals in a population to die. seasonal temperature changes cause a species to migrate between two ecosystems. excessive rain and flooding cause organisms in an area to relocate. the population of a predator increases following an increase in the population of its prey.

The population of a predator increases following an increase in the population of its prey.

Explanation:

Biotic factor is the factor of the ecosystem which includes all the living beings such as animals, microbes, birds, insects and plants.

Population dynamics can be define as the branch of biology which studies the size and age composition of the population. It is influences by the birth rates, death rates, immigration and  emigration.

The population of predator is the biotic factor which is affecting the population of the prey. As with the increase of the predator population the demand for food will increase hence, the population of the prey should also increase. This is going to affect the population dynamics of the ecosystem.        

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
