Answer 2

Answer: Immigration is more than emigration

Explanation:

Immigration can be defined as the entry of number of organism due to resources or any other reason.

Whereas, emigration of species can be defined as the moving out of the number of organism due lack of resources.

The overall change in the population of the species is due to the entrance of the same species population on to a particular place as compared to that of emigration.

So, because of this reason the population of a species will increase in number.
