Biotic and abiotic factors are the environmental conditions that the organisms have to face to live in a specified environment.

Abiotic factors
Abiotic factors are the physical and chemical conditions of an environment. For example : heat, salinity, pressure, light, wind, pH ...

Biotic factors
Biotic factors are all the biological conditions of an environment for a specie/taxa. It can include prey and predator abundance, available food amount, available space, intra and interspecific competition...

The development of organims is under the control of abiotic factors. Some are adapted to heat, cold etc ... The abiotic factors will define which organisms are able or not to live in a specified place.

The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment.

So, the abiotic factors are controling the biotic factors of an environment.

Hope it helps you !

Everything depends on another significant part.


Abiotic factors support plant development. Let me explain this:

If soil organic carbon is rich, you can see your tree or plant become healthier if sufficient water and sunlight exist. In general, organic matter (organic carbon) in the soil improves plant growth.

To a farmer, the bottom line for deciding a good level of organic matter to maintain at his/her field relies upon cost and convenience. A practical rule is to use all available crop residues (leaves, stems, etc.) by incorporating them into the soil, apply the minimum fertilizer economically feasible to produce maximum plant size for greater harvests, and add other suitable residues that might be available. Minimizing erosion is another solution since erosion transports upper organic matter into other areas.

Macro and micronutrients should be in optimum concentrations to support plant life in an area. When they are missing, you can see some problems in plants.
