Ans. Biotic components of the environment refer to all living things such as plants, animals, and microorganisms. Abiotic components of the environment refer to all non-living things such as air, water, soil, and climate. While biotic components are dependent on abiotic components for survival, abiotic components do not require biotic components to exist. Both biotic and abiotic components are interconnected and interact with each other to form an ecosystem.
