The graph shown represents the population growth curves of two different species of aquatic organisms, A and B. What is the valid prediction based on this graph?

Species B will increase in population size approximately 1 month after an increase in the population size of Species A. Species B will increase in population size approximately 1 month after an increase in the population size of Species A. Species B will attain maximum population size each autumn due to a decrease in water temperature. Species A will not be present in the water during the winter months. Species A will not be present in the water during the winter months. Species A will eliminate Species B from the water after 1 year. Species A will eliminate Species B from the water after 1 year.

1 answer

The valid prediction based on the graph is that Species B will increase in population size approximately 1 month after an increase in the population size of Species A. This is because the population growth curve of Species B follows closely behind that of Species A. There is no evidence in the graph to support the other predictions.
