Summary Introduction
Introduction:
Population on earth is very vast and it comprises all individuals including flora and fauna. The estimation of species is done depending upon the size, age, and other factors. These features help in classifying the organism in a given population.

A population’s ecological footprint is measured in terms of:
a
how many resources the population uses.
b
how much land area is needed to support its lifestyle.
c
the amount of waste/pollution it produces.
d
the number of people who live there.
When discussing population size, we are referring to
a.
the total number of individuals in a population.
b.
the size of the geographic region in which a population is found.
c.
the number of individuals in a population divided by the area of the region covered by the population.
d.
the number of individuals in a population multiplied by the area of the region covered by the population.
e.
the specific type of environment in which a population can exist.
The relative abundance of any one species within a community of many species is known as
a.
species evenness.
b.
species richness.
c.
specialization.
d.
