What happens when the most
limiting factor in an ecosystem is
removed?

The answer is A, population growth increases .

—Explanation—
•] The definition of limiting factor; anything that constrains a population's size and slows or stops it from growing.
•]Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources.
•] So if the limiting factor is removed then the population begins to expand due to not having a factor that limits each species quantity.

It's cell theory. easy name i would think.
