Answer 2

Ans.

Death rate or mortality rate can be defined as the total number of deaths in per thousand organisms in a population, per unit time. It can be calculated by dividing the total number of deaths by the total number of organisms in that population, and them multiplied by thousand.

Thus, death rate for given population of butterflies wound be:  $\frac{8}{80}\times1000 = 100$
