In change in population size, Nt = N0 + ...

In change in population size, `N_t` = `N_0` + B + I - D - E. What do I, B, D stand for?

A

Immigration, mortality, natality

B

Immigration, natality, mortality

C

Emigration, natality, mortality

D

Mortality, natality and immigration

Text Solution

Verified by Experts

The correct Answer is:
B

Whatever might be the ultimate reasons, the density of a population in a given habitat during a given period, fluctuates due to changes in four basic processes- metality, mortality, immigration and emigration.
