Question

Long-term studies of certain species of squirrels in California revealed that some of the squirrels move nearly two kilometers from where they are born.
What influence would this migration have on the density of the local population they move into?

A.the density of the local population with increase
B.the density of the local population will decrease
Cthe density of the local population will stay the same

Answer 1

The question was asking to choose among the following choices that could influence the migration have on the density of the local population taht they move into and in my research I would say that itsletter  A.the density of the local population with increase. I hope this would help

Answer 2

Answer:

The correct answer is option A, the density of the local population with increase

Explanation:

We can understand this from an example. Suppose there are two ecosystems A and B

Now in ecosystem A, 100 new squirrels are produced which later on move to a new ecosystem B (located at a distance of 2 Km from ecosystem A). Let's suppose the initial squirrel population was 100 in ecosystem B. After the migration of 100 new squirrel,  the new population of squirrel in ecosystem B becomes 200.  

Since population density in directly proportional to the population of a species, the increase in population of squirrel in ecosystem B , would definitely lead to an increase in population density of squirrel in ecosystem B
