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

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
