1 The base of geometric logarithms
2 The base of number logarithms
3 The base of exponential logarithms
4 The base of natural logarithms
Explanation:
Exp. (D) In the exponential growth equation $\mathrm{N}_{\mathrm{t}}=\mathrm{N}_{\mathrm{o}} \mathrm{e}^{\text {rtt }}$. - $\mathrm{e}=$ represent the base of natural logarithms. - $\mathrm{N}_{\mathrm{t}}=$ population density after time $\mathrm{t}$. - $\mathrm{N}_{\mathrm{o}}=$ Population density at time zero. - $\mathrm{r}=$ Intrinsic rate of natural increase called biotic potential.

The species confined to a particular region and not found elsewhere is termed as :
1 Rare
2 Keystone
3 Alien
4 Endemic
Explanation:
Endemic species are those that are restricted to a geographical area and do not occur naturally in any other part of the world. - A keystone species is an organism that helps defines an entire ecosystem. - Alian species are species that occur outside their natural range and dispersal potential.

Natality refers to
1 Death rate
2 Birth rate
3 Number of individuals entering a habitat
4 Number of individuals leaving the habitat
Explanation:
The term Natality refers to birth rate. - Natality is the average number of new individual born by a population in a unit of time (per year). It can be expressed as the number of birth per. - Mortality refers to death rate - Number of individual entering a habitat is immigration. - Number of individual leaving the habitat emigration.

Niche is
1 all the biological factors in the organism's environment
2 the physical space where an organism lives
3 the functional role played by the organism where it lives
4 the range of temperature that the organism needs to live
Explanation:
Niche is an ecological component of habitat which is delimited by the functioning of an organism. - The term niche was describe by J. Grinnell it refers functional role played by the organism where it lives. - A species may live in more than one niche in different stage of life cycle. - Without the ecological niches, there would be less biodiversity and ecosystem would be in balance.
