The graph below shows the changes in two populations of herbivores in a grassy field. A possible reason for these changes is that

Options

  1. Apopulation B competed more successfully for food than population A did.
  2. Ball of the plant populations in this habitat decreased.
  3. Cpopulation A consumed the members of population B.
  4. Dpopulation A produced more offspring than population B did.

Correct answer

A. population B competed more successfully for food than population A did.

Step-by-step solution

If population B increased while population A decreased, these organisms were probably in competition for the same food (grass) and population B was better adapted. Hence population A is competitively being excluded from the population.
