A parasite that invades a host can reproduce and cause a decline in the host species population.
|
|
|
Organisms that compete for the same resources will keep each other from overpopulating.
|
|
|
Predators will prevent herbivores from depleting the plants and other resources in an ecosystem.

|
|
Seasonal variations in temperature can cause some of the individuals in a population to die.

Detailed explanation-1: -Which of the following describes how an abiotic factor can impact the population dynamics in an ecosystem? Predators will prevent herbivores from depleting the plants and other resources in an ecosystem. Seasonal variations in temperature can cause some of the individuals in a population to die.
Detailed explanation-2: -Some abiotic limiting factors affect members of a population because of the population density. These things include disease, food supply, and increased predation. Diseases and parasites are more easily transmitted in larger populations. More individuals mean increased competition for the food that is available.
Detailed explanation-3: -Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations. They help determine the types and numbers of organisms able to exist within an environment.
Detailed explanation-4: -These influences can involve biotic interactions like competition, predation, and disease, or abiotic factors like severe weather, flooding, drought, and fire. Most species appear to be limited in at least part of their geographic range by abiotic factors, such as temperature, moisture availability, and soil nutrients.
Detailed explanation-5: -Temperature, pH, light, water and soil are the major abiotic factors that affect living organisms and the functioning of ecosystems.
