Question

Read the following statements carefully :

Statement I : Population explosion, affluent consumption and production have placed a huge stress on the environment.

Statement II : Carrying capacity is the largest size of a density-dependent population for which the population growth rate is zero.

In the light of the given statements, choose the correct option from the following :

• A. Statement I is true and Statement II is false.
• B. Statement I is false and Statement II is true.
• C. Both Statements I and II are true.
• D. Both Statements I and II are false.

Hint:

Population pressure with affluent consumption strains the environment, and carrying capacity is the maximum sustainable population with zero growth. Both are true.

Answer 1

The Correct Option is C

Step 1: Understand the task:
We check two statements one by one. Both are about the environment and population.

Step 2: Check Statement I:
A fast rising population needs more food, water, land and energy. Rich lifestyles and high production use even more resources and create more waste.
This puts heavy stress on the environment, so Statement I is TRUE.

Step 3: Check Statement II:
Carrying capacity is the largest population of a species that the environment can support. At this size the growth rate becomes zero.
Growth depends on density, since food and space run short as numbers rise. So Statement II is TRUE.

Step 4: Match with the options:
Both are true, so option (C) is right.
(A) and (B) wrongly call one statement false. (D) wrongly calls both false.

Final Answer:
Both Statements I and II are true. Option (C).
