Question

Name various components of environment that determine the population growth.

Answer 1

Population growth at any instant is defined by the difference between the total number of organisms added and the total number of organisms lost.

Population growth = organism added - organism lost.

Various components of the environment that determine population growth:
1. Biotic potential :

• It is the physiological capacity of organisms to supply offspring.
• It is known as reproductive potential.
• The maximum value of biotic potential is not obtained due to many factors in the environment like shortage of food, premature death, etc.

2. Environmental resistance:

• It is the sum of different factors that do not permit the survival of all the members of a species.
