The following graph depicts changes in two populations (A and B) of herbivores in a grassy field. A possible reason for these changes is that Bask in sun when temperature is low.

Question

The following graph depicts changes in two populations (A and B) of herbivores in a grassy field. A possible reason for these changes is that Bask in sun when temperature is low. (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.

Both the populations are herbivorous, thus they cannot each other. If the food sources for these populations A and B have decreased, then both the populations A and B would have declined. If population A have produced more offspring then the graph A should have increased. Based on the graph. Population B is more successful in competing with population A, that is why number of organisms in population B increased while that in population A decreased, as they get access to limited resources.

Q. The following graph depicts changes in two populations (A and B) of herbivores in a grassy field. A possible reason for these changes is that Bask in sun when temperature is low.

Population A produced more offspring than , population B

Population A consumed the members of population B

Both plant populations in this habitat decreased

Population B competed more successfully for food than population A.
