Two kinds of components
Both a pond and a forest habitat have living beings and non-living things. The living beings are the biotic components. The non-living things, such as air, sunlight, water, temperature and soil, are the abiotic components.
Biotic components: the living beings of a habitat. Abiotic components: the non-living things such as air, sunlight, water, temperature and soil.
Notes
Biotic = living. Abiotic = non-living (air, sunlight, water, temperature, soil).
