Question

A population of squirrels living in a habitat covering 150 hectares is at 80% of the carrying capacity of 1,500. Assuming that the squirrels have a uniform distribution, what is the population density of the squirrels?
The population density of the squirrels is_____

Answer 1

1) To calculate the population density you first need to know how many squirrels form that population.
To calculate the number of squirrels:
1500 squirrels is the capacity, so it's equivalent to 100%
So how much squirrels are present in 80% of the area:
1500----100 %
x----------80 %
x= 1200 squirrels
 
2)Population Density equals the number of squirrels divided by the land area
In the first part was calculated the number of squirrels and the exercise gives us the area in hectares so the only thing left to do is divide them.
(since this exercise doesn't specify that the area needs to be in a certain measurement we can use hectares)
 Population Density = 1200/ 150
The population density of the squirrels is 8 per hectare

Answer 2

15 scquirrels per hectares I think
