Abiotic Components:

These are the inorganic components of the ecosystem like humidity, temperature, etc.

These are the non living components of the ecosystem which includes physical and chemical constituents of the environment which influences the biotic components and the ecosystem's functioning.

The abiotic components influences certain behaviors in living organisms like reproduction, growth, etc.

These components are synthesized by the process of photosynthesis by utilizing sunlight to convert these into organic compounds by primary producers which are further are the consumption of secondary producers thus increasing the organic content.
