In a certain ecosystem, owls are predators for mice. the owl population increases, and they eat more mice. this causes the mouse population to decrease. what happens next?

the birthrate of owls increases
the birthrate of mice increases
the population of owls decreases
the population of mice increases

C. The population of owls decreases.

Owls are known to be a predator that depends on mice or other animals for food In order to survive. However, increase in population of owls will automatically crash the population of the mice or other prey species as the owls eat them and this will lead to a resultant crash in owls population.

Option C, the population of owls decreases

Explanation:

The growth of population of owl is linked with the adequate supply of food i.e mice.

The higher the population of mice , the higher will be the population growth of owls.

Thus, As the population of mouse decreases, the owls will not get sufficient food. There will be scarcity of food which will lead to the survival of the fittest owl only and hence the owl population will decrease eventually.

Hence, option C is correct

a time line cause it goes from 685 to 978
