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.
These may be plants, animals, fungi, and any other living things. Abiotic factors are all of the non-living things in an ecosystem. Both biotic and abiotic factors are related to each other in an ecosystem, and if one factor is changed or removed, it can affect the entire ecosystem.
