Balance
If you look at the size of populations of animals in an ecosystem, you notice an interesting thing. Balance is always achieved through time. This is something I learned in my biology class. You can probably find this for yourself by searching for animal populations and Biology online. Basically, you will see if one population is larger or smaller, it will affect the other populations. Let's take an example. You have a predator like a Lion, and you have a herbivore like a Gazelle. So lets say that there are very few Lions. How does this affect the Gazelle population do you think? In case you didn't know, the Lion's eat the Gazelle for food. What biologists have observed and recorded is that the population of Gazelle will increase when there are fewer predators to hunt them. But later in time, what happens is that the Lion population will grow because the Gazelle population has grown so much. Presumably this is because it is much easier to catch a Gazelle because there are ...
