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.        

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
