Answer:
limit the number of plant populations that can grow in an ecosystem.
Explanation:
All living organisms have basic needs, such as food, minerals, water, shelter, and sunlight. If there were an unlimited supply of these items, populations could continue to grow indefinitely. This, however, is not the case. Living factors, such as animals and plants, and nonliving factors, such as water, minerals, and sunlight, are often called limiting factors, because there is a finite supply and they limit the number of populations that can grow and thrive in an ecosystem.
