Botany-Population Growth
NEET Botany Population Growth MCQ Question
Type: MCQ-numerical-Medium-Class 12
If a population of a certain species is initially 1000 and grows to 4000 in 6 years, what is the intrinsic rate of increase (r) assuming exponential growth?
A
0.231
B
0.462
C
0.115
D
0.693
Correct Answer
Option A
Detailed Explanation
The intrinsic rate of increase (r) can be calculated using the formula N(t) = N0 * e^(rt). Given that N(t)/N0 = 4000/1000 = 4 and time t = 6, solving e^(6r) = 4 gives r ≈ 0.231.
