abiotic factors
Abiotic factors are the factors in an ecosystem that are not, nor ever will be, living. Abiotic factors play a very big roll in the enviornment, with out them, there wouldn't really even be much of anyhting to call an enviornment. Just think about the world if there was not a sun, weather, climate, etc. Without those things, that area would not be liveable. For example, almost every ecosystem is dependent on the sun for their energy, and sunlight is essential for plant growth. So, you cannot have an ecosystem without it, and that just shows the importance of having abiotic factors.
