relationship between biotic and biotic components in a forest

Dear student,
 
The question you have asked should be "Relationship between biotic and abiotic components of forest" 

Biotic and abiotic components are the inseparable part of a forest ecosystem. In a forest, biotic components are the living one which includes all the plants in a stratification from smaller to the larger one, all kinds of animals and microbes etc. Abiotic components are non-living which includes sunlight, nutrients present in the soil, edaphic factors and moisture. 
The relationship between biotic and abiotic components of a forest ecosystem is that -
Abiotic component like nutrients, moisture along with energy interact with biotic components and makes them alive and forms a functional ecosystem by the cycling of matter between biotic and abiotic components.

Regards.
