When a population grows to large and there are not enough rescources for them to survive so they "boom" up and "bust " back down.

Myra is pretty much right -- when a population grows at exponential or near-exponential rates, then either outstrips its resources or the population density becomes so high that other limiting features kick in, such as endemic disease, or stress inhibiting breeding, at which point the death rate outstrips the birth rate and the population level crashes.
