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.
1. Abiotic elements are those that are non-living, but affect the ecosystem. Examples of these include water, heat, relief, the atmosphere, soil, fire, gravity, nutrients and rocks. 2. Biotic elements are those living elements of the ecosystem.In other words the plants and animals.Within the biotic element, there are organisms, which are known as producers. These convert sunlight into energy through the process of photosynthesis.hese primarily relate to the climate and soil seen in the ecosystem. Climate, soils and vegetation interact closely to produce the characteristic nature of an individual ecosystem. Ecosystems can be split into two main sections, abiotic and biotic elements: 1.
