Answer 1

Answer:

Intrinsic growth rate (r) or Malthusian parameter difference between birth rate and mortality rate per census. When the ‘r’ value is high, the growth rate accelerates. It can be expressed as, r = (b-d)

where,

b birth rate which is the total number of children born live in the community per year

d death rate which means the total number of deaths per year

We have

r = (b - d)

birth rate is the rate at which birth is taking place.

death rate is the rate at which death is taking place.

For the Norwegian rat, r is 0.015, for the beetle, r is 0.12 and for the Indians in 1981, the r value is 0.0205.
