Question

It takes 88 years for a popuaiton to grow from 1,200 individuals to 4,800 individuals what is the instristic rate of growth?

Answer 1

Answer:

3.43

Explanation:

Data provided in the question:

Time taken for the given growth in population = 88 years

Initial population, n = 1,200

Total population, N = 4,800

Now,

we know

Total population is given as:

N = n + [ rn( (k - n) ÷ k ) ]

here,

r is the intrinsic growth rate

k is the Carrying capacity = 2N = 2 × 4,800 = 9,600

on substituting the respective values, we get

4,800 = 1,200 + [ r × 1,200( (9,600 - 1,200) ÷ 9,600 ) ]

or

3,600 =  r × 1,050

or

r = 3.43
