Question

An unrestricted reproductive capacity is called as?

Answer 1

Hint: Reproductive capacity is defined by the number of individuals per species that can be produced by an organism which can also be defined as biotic potential.

Complete answer:
Unrestricted reproductive capacity is the number of organisms that individuals can produce in favourable condition.
factors that can affect the reproductive potential are as follow:
1. Unfavourable climate condition
2. Lack of space light or suitable substrate
3. Deficiency of chemical compounds.
4. Inhibiting effects generally as parasites disease, unfavourable environment, genetic changes.
Biotic potential is the quantitative expression that expresses the ability of a species to face selection in an environment. It can be described in the following equation.
Number of individuals = biotic potential or resistance of the environment.
So Biotic potential is described as unrestricted growth of population resulting in maximum growth of population.
Full expression of biotic potential in a species leads to an increase in reproductive rate. The reproductive curves increase in the form of exponential growth. This only reaches when environmental conditions are favourable. such species are said to have a high fertility rate.

Note:
Chapman related biotic potential with vital index. We can also find the surviving rate of species by vital index.
Vital index = (no. of birth/no of death)*100
