Biotic components include:
1) Producers- These organisms are also called autotrophs as they prepare their own food with the help of photosynthesis and include trees, herbs, shrubs, and other plants and cyanobacteria.
2) Consumers- These organisms are also called heterotrophs and are dependent on the autotrophs directly or indirectly for their energy requirement.
3) Decomposers- These organisms are also known as detritivores. They are heterotrophic saprophytes which consume dead and decaying matter also called detritus.
