Question

There were 770 frogs in a pond. 70 of-them died within a month.

Calculate the death rate of the population of frogs in the pond.

Answer 1

Death rate (Mortality) is calculated as the number of deaths divided by the initial population size.

Key Formula or Approach:

Death Rate = `"Number of details"/"Initial population size"`

Number of deaths = 70.

Initial population = 770.

Death Rate = `70/770 = 1/11 ≈ 0.0909`

The death rate is 0.0909 per frog per month.
