Question

Assertion[A]: With increase in population size, environmental resistance tends to increase.
Reason[R]: This nature’s way to check the expression of biotic potential

• A. Both assertion and reason are true and the reason is the correct explanation of assertion
• B. Both assertion and reason are true but reason is not the correct explanation of assertion
• C. Assertion is true but reason is false
• D. Assertion is false and reason is true

Answer 1

The correct option is A Both assertion and reason are true and the reason is the correct explanation of assertion

The inherent maximum capacity of an organism to reproduce or increase in number is termed biotic potential. Biotic potential is realized only when the environmental conditions are non-limiting, so that natality rate is maximum and mortality rate is minimum. However, nature keeps a check on the expression of biotic potential. With increase in population size, the environmental resistance tends to increase.
