Explain how the carrying capacity of an ecosystem causes a population to decrease in size.
Answers
Answer:
In a population at its carrying capacity, there are as many organisms of that species as the habitat can support. If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.
Answer:
Biotic and abiotic factors determine the population size of a species in an ecosystem. What are some important biotic factors? Biotic factors include the amount of food that is available to that species and the number of organisms that also use that food source. What are some important abiotic factors? Space, water, and climate all help determine a species population.
When does a population grow? A population grows when the number of births is greater than the number of deaths. When does a population shrink? When deaths exceed births.
What causes a population to grow? For a population to grow there must be ample resources and no major problems. What causes a population to shrink? A population can shrink either because of biotic or abiotic limits. An increase in predators, the emergence of a new disease, or the loss of habitat are just three possible problems that will decrease a population. A population may also shrink if it grows too large for the resources required to support it.
