Question

If in a population the natality is 20 and mortality is 10, in a span of 10 years. What is the growth rate (GR) of that population?

(a) 0

(b) 20

(c) 1

(d) -10

I have been asked this question in an online interview.

Question is taken from Population Growth in portion Organisms and Populations of Biology – Class 12

Answer 1

The correct answer is (c) 1

The explanation: As per the formula, GR = \(\frac{Natality – Mortality}{Unit \, time} = \frac{20 – 10}{10}\) = 1

The growth rate of the given area is 1 in 10 years.
