Answer:
15 blue jays per 1 hectare
Step-by-step 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
