A biological community of interacting organisms and their physical environment is called ecosystem.a large naturally occurring community of flora and fauna occupying a major habitat, e.g. forest or tundra.is a biome.Biotic components are the living things that shape an ecosystem. A biotic factor is any living component that affects another organism, including animals that consume the organism in question, and the living food that the organism consumes.In ecology and biology, abiotic components are non-living chemical and physical factors in the environment, which affect ecosystems. Abiotic phenomena underlie all of biology. In biology, abiotic factors can include soil acidity, light, radiation, temperature, water, atmospheric gases, and soil. There are different types of biomes such as tropical forests, grasslands, desserts, mountains, tundra,etc.
