Question

The above graph depicts changes in two populations (A and B) of herbivores in a grassy field A, possible reason for these changes is that

• A. Population A produced more offspring than population B.
• B. Population A consumed the members of population B.
• C. Both plant populations in this habitat decreased.
• D. Population B competed more successfully for food than population A.

Answer 1

The correct option is D Population B competed more successfully for food than population A.

The two populations A and B are herbivores which are competing for the same food. Population A decreased as it was not well adapted as population B. Population B was able to strive for the available food.

So, the correct answer is option D.
