Sunlight, soil, water, and pollution, for example, are all important abiotic factors of an environment that affect life. The biotic environment, on the other hand, is composed of all the living organisms in an ecosystem, and includes factors such as disease, predators, prey, and human activity.
There's numerous biotic and abiotic factors of an ecosystem. Some include: abiotic: cool summers, windy conditions, heavy precipitation, fast flowing rivers, fast changes in a â¦ ltitude, and the temperatures vary with elevation. biotic: wildlife animals in the mountain forest like grizzly bears, cougars, etc.biotic factors are non-living parts of the environment that affect living organisms. The broad range of abiotic factors can be divided into two main categories: the physica â¦ l environment (terrain type, amount of water present, soil fertility) and weather (wind, cloud cover, temperature).
