NEET Botany Population Growth MCQ Question

Type: MCQ-numerical-Easy-Class 12

If a population of 1000 individuals grows exponentially and doubles in size in 3 years, what is its intrinsic rate of increase (r) per year?

A

0.231

B

0.693

C

0.100

D

0.301

Correct Answer

Option A

Detailed Explanation

The intrinsic rate of increase (r) can be calculated using the formula N(t) = N(0) * e^(rt). Given that the population doubles in 3 years, N(t)/N(0) = 2, and solving for r gives r = ln(2)/3 ≈ 0.231.
