Explain what a limiting factor is, then explain what carrying capacity is.  Now explain how changing a limiting factor would change the carrying capacity of an environment.  

Limiting factors are anything that will control the population of a species.  The carrying capacity is the largest population an environment can support over a long period of time.  If a limiting factor is changed by reducing the pressure it puts on the population, the carrying capacity can grow.  If the pressure from the limiting factor is increased, the carrying capacity should go down
