Abiotic and biotic limiting factors.

       A limiting factor is something that can be abiotic or biotic ( living or nonliving) that can cause a population to go up and down.
       A biotic limiting factor could be a coyote or wolf. They could have an effect on carrying capacity could be that when a population like rabbits is high the coyotes will have lots of food, and since the population is high and the coyotes are hunting them the population will go down.
        An abiotic limiting factor could be a fire or any other natural disaster. Fires could have an affect on the population of rabbits because it could burn their habitat and food. Floods could also have an effect because they could cover all of their habitat and food in water, some rabbits could even drowned.
