Question

Competition for light, nutrients and space is most severe between

• A. Closely related organisms growing in different niches.
• B. Closely related organisms growing in the same area/niches.
• C. Distantly related organisms growing in same habitat.
• D. Distantly related organisms growing in different habitat.

Answer 1

The correct option is B Closely related organisms growing in the same area/niches.

When two closely associated species, that have the same feeding habits, and exhibit similarities, stay together, they compete with each other. They show competition for food, shelter and other daily requirements of life. When they live in the same habitat, their requirements clash, and competition between them increases. As a result, they struggle for their existence and the fittest among them can survive.

So, option B is the correct answer.
