NEET Botany Population Growth MCQ Question

Type: MCQ-numerical-Hard-Class 12

A population of rabbits in a forest is growing exponentially. If the population doubles in size in 3 years, what is the intrinsic rate of increase (r) of the population? Use the formula N(t) = N(0)e^(rt). Assume the initial population size N(0) is 1000.

A

0.231

B

0.693

C

0.500

D

0.333

Correct Answer

Option A

Detailed Explanation

Using the formula N(t) = N(0)e^(rt), where N(t) = 2000, N(0) = 1000, and t = 3, solving for r gives r ≈ 0.231. This matches the intrinsic rate of increase for exponential growth as described.
