Limiting Factor
Limiting factor explained in an easy to understand way:
Imagine trying to make a large pot of soup, but you're running out of water. Just as your soup can't grow without enough water, a population can't grow if a crucial resource, like water during a drought, is limited. In both cases, the lack of water is the limiting factor that prevents further growth—your soup won't fill more bowls, and the population won't increase beyond what the environment can support.
