Question

If the birth rate of a population of dolphins is 2.0, the death rate is 0.5, and the population size is 100, what is this dolphin's population growth?

Answer 1

Answer:

Dolphin's population growth is 0.015

Explanation:

The birth rate of the population is B= 2.0 and the death rate is D = 0.5

The population size is N=100.

Hence, dolphin population growth is given by

$r=\frac{B}{N}-\frac{D}{N}\\\\r=\frac{2}{100}-\frac{0.5}{100}\\\\r=0.015$

Thus, dolphin's population growth is 0.015
