Neet Solved Paper 2015 Question 87
Question: The following graph depicts changes in two populations (A and B) of herbivores in grassy field A possible reason for these changes is that
Options:
A) both plant populations in this habitat decreased
B) population-B competed more successfully for food than population-A
C) population-A produced more offspring than population-B
D) population-A consumed the members of population-B
Show Answer
Answer:
Correct Answer: B
Solution:
- The graph shows changes in two populations (A and B) of herbivores in a grassy field. To determine the possible reason for these changes, let’s analyze the options:
A) Both plant populations in this habitat decreased: If the plant populations decreased, it would likely affect both herbivore populations similarly, unless one population had a competitive advantage. This option does not directly explain the observed changes in the graph.
B) Population-B competed more successfully for food than population-A: This option suggests that Population-B was better at obtaining food resources, which could lead to an increase in Population-B and a decrease in Population-A. This explanation aligns with the observed changes in the graph, where Population-B increases while Population-A decreases.
C) Population-A produced more offspring than Population-B: If Population-A produced more offspring, we would expect to see an increase in Population-A rather than a decrease. This option does not explain the observed changes in the graph.
D) Population-A consumed the members of Population-B: Since both populations are herbivores, it is unlikely that Population-A would consume members of Population-B. This option does not fit the context of the graph.
