Asquare kilometer of forest has 200 deer. what is the term that is used to describe this number?
() density dependant
() birth rate
() limiting factors
() population density

Answer;

-Population density

Explanation;

- Population is a group of organisms of the same species who live in the same area at the same time. Population density is the number of individuals in an area of a specific size.

-Population density is calculated by dividing the population by the area. For example, Francce has a population of 60,561,200, and an area of 551,695 square kilometres, so its population density is about 109.8 persons per square kilometre.

the right option is; decreased genetic variation  

decreased genetic variation describes the effect of this environmental change.

genetic variation is the naturally occurring genetic diversities or differences between organisms of the same species in a population. genetic variation allows the survival and adaptability of a species when they encounter changing environmental conditions. when an endangered species reduces, it loses genetic variation which may not be restored even if the species rebound and will only be recovered through the gradual collection of mutations over many years.
