In a forest ecosystem, wolves prey on rabbits. The graph below shows that the relationship between the populations of rabbits and wolves over time follows a predictable pattern. Which of the following best explains this natural phenomenon? The rabbit population decreases as the rabbits migrate to escape predators, and the wolf population decreases as the wolves follow their prey. <-- choice The rabbit population increases after a decrease in wolf population because wolves and rabbits compete for some of the same resources. The populations of wolves and rabbits increase at the same rate when environmental conditions are favorable and decrease when conditions are unfavorable. The wolf population increases after an increase in rabbit population, and then decreases when rabbits are less readily available. Not sure though my brother gave me the answer to this i don't know

OpenStudy (abhisar):

Do you think option 2 is correct?

OpenStudy (anonymous):

yeah according to the graph that what i thought because the red line is increased then the blue one so i feel like since there is less wolfs there would be more rabbits and if it was more wolves it would be less rabbits but i feel like my brother only tld me to choose A to leave him alone and not bug him

OpenStudy (abhisar):

But rabbits and wolves don't depend on same resource...

OpenStudy (anonymous):

that's true

OpenStudy (anonymous):

so it is A?

OpenStudy (abhisar):

One min

OpenStudy (abhisar):

Since, wolves predate on rabbits, they are dependent on rabbits. If population of rabbit increases, population if wolves will also increase and if population of rabbits decreases then population of wolves will also decrease.

OpenStudy (abhisar):

But i find third option correct too

OpenStudy (anonymous):

Okay thanks i really appreciate your help
