Summative Summary Questions
1. Using an example, describe why a population could not increase for ever.
Because in some point if their is a lot of predators they wont be so much preys so the predators would decrease and the preys would start increasing and then the population of preys would start overpopulating the whole animal population so that's why we need predators so they can control the prey population.
2. What are the 2 factors that determine whether a population increases or decreases.
The first factor is the predators, and the second factor is the preys, because they determine the population of the whole predators. If we wouldn't have preys then the predators would starve to death because they wouldn't have anything to eat except themselves.
3. Give a reason why the human population of earth has continued to increase so much for the past hundred years?
First, because nothing eats us, we are the predators. And second, each day at least 400 babies are born, so the population is going to keep on growing and growing. In my personal opinion I think that the world is going to reach a point that the world would be completely overpopulated of humans.
