Biotic and abiotic factors are the two components of an ecosystem. Biotic factors are the living things, like plants, animals, and fungi. Abiotic factors are non-living things, like air, soil, water, and sunlight. Every ecosystem includes both biotic and abiotic factors. Abiotic factors determine the type of life that lives in the ecosystem.Web
The audible periodic table is proving its intrigue for music and science alike.
