Question

You are studying the population growth of a species of fish. Assuming unlimited resources, no predators, and a constant per capita growth rate, if the population size in 2018 was 1100 and the population size in 2019 was 1500, what will the projected population size be in 2030? when inputting your answer, write a whole number (e. G. , 1100, 1200, 1500) without decimals. If your calculation includes decimals, round up to the nearest whole number if your decimal is 0. 5 or larger, round down if your decimal is below 0. 5.

Answer 1

The projected population size in 2030 will be : ≈ 44159

First step : determine the population growth rate

Gr = change in population / time

    = ( 1500 - 1100 ) / 1 year

    = 400 = 36%

Determine the projected population size

applying Malthus's population projection.

Pp = P₁ ( 1 + r )ⁿ

where ; P₁ = 1500, r = 0.36 , n = ( 2030 - 2019 ) = 11 years

Pp = 1500 ( 1 + 0.36 )¹¹

    = 1500 ( 29.439 )

    = 44158.5  ≈ 44159

Hence we can conclude that the projected population size as at 2030 is 44159
