Biotic Factors
Biotic Factors are any factos in the enviornment that are living or once living. It is not very hard to distinguish the biotic factors. With out these factors in the enviornment, there would be no competiton, predation, or symbiosis, and some of the things that were competed for would over populate. In some ecosystems, such as a jungle, there are many more biotic factors than there are abiotic factors. But, in ecosystems, such as the desert, the biotic factors are limtied because because of the abiotic factors in that ecosystem.
