Use the graph to answer the question below. Analyze the graph and identify some factors that may contribute to the rotifer population leveling off in the absence of water fleas. Explain your answer in 1–2 sentences.

One factor that may contribute to the rotifer population leveling off in the absence of water fleas is resource limitation. As the population of water fleas decreases, the rotifers may experience competition for food and resources, which could limit their population growth and eventually lead to a plateau in their population size.
