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: The dolphin's population growth is 150% .

Step-by-step explanation:

The birth rate of dolphins =
`2.0=(2.0* 100)/(100)=200\%`

The death rate of the dolphins =
`0.5=(0.5* 100)/(100)=50\%`

Dolphin's population growth = Birth rate - Death rate

=
`200\%-50\%=150\%`

The dolphin's population growth is 150%.
