If 300 blue jays are found in a 20 hectare plot, what is the population density?

15 blue jays per 1 hectare

Explanation:

==>Given:

A population of blue jays (N) = 300

Area of land (A) = 20 hectares

==>Required:

Population density (D)

==>Solution:

Population density can be defined as the number of members of a population dwelling in a unit area.

The formula is given by:

Population density (D) = Population (N) : Area (A)

Thus, D = 300 : 20

D = 15

Population density of blue jay = 15 blue jays per 1 hectare
