Further Explanation; Ecosystem  An ecosystem is a community where living things and non-livings live together and interact to enhance survival.  Factors affecting an Ecosystem Biotic factors These are living factors that affect an ecosystem. They include living things such as animals, microorganisms and plants.  These factors have an effect on other living things in the ecosystem in various ways. The ways through which biotic factors affect other organisms in an ecosystem includes: Biotic factors may be classified into: Producers They are also known as autotrophs, they convert solar energy from the sun into food through the process of photosynthesis. They are mainly plants.  Consumers These are known as heterotrophs, they lack the ability to make their own food and thus rely on producers for food.  Decomposers Also known as detritivores, they break down chemicals from consumers and producers into simpler form that may be used again.  Biotic factors participate in the food web and thus they rely on each other for their survival. Abiotic factors  These are factors in an ecosystem that affect and influence living organism in an ecosystem. Abioitic factors are non-living factors, they include; water, salinity, gases, rainfall, temperature, etc.
