                                              BIOTIC AND ABIOTIC ENVIRONMENT

In general the surroundings of an organism living in its natural habitat is termed as

environment. These surroundings include all; physical, mental and spiritual conditions.

The human beings are so complex in nature that it is a combined effect of every thing,

which exists, far or near them, affects their life (mental, physical and spiritual). 

The gravitational forces of distant planets affect each other and these movement or rotation

is based on the balance between them. Tides come because of the gravitational attraction

of moon and sun, which move the bodies of water on the earth as well as the water,

which is the main constituent of human body (75%). It has been well established that

the non-living things and the living beings are totally interrelated and dependent on each

other. It is only a matter of time that something is nonliving or somebody is living being.

We consume the food, which becomes part of our body cells and gets changed into living

being. After the death of those cells or the whole body it again becomes non-living. So

it is a combination or synthesis of various elements with some unknown factor like soul

that demarcates the living beings and non-living things. But it is sure that nature is in

dynamic equilibrium of both of them. Thus we can classify the environment 

                                                              

 Physical or abiotic environment

It consists of physical factors Land (minerals, toxic elements, nutrients), sky (sink of

various things, noise) and air (useful and other gases). Anciently, we have realized this

combination as “ Ksiti (Earth), Jal (Water), Pavak (Fire), Gagan (Sky), Sameera (Air):

the five basic elements (Panch Tatva) which influence life.

 Living or biotic environment

It consists of plants, animals (including human beings) and micro-organisms. Life in

the form of micro-organisms is very strange and subtle (strong). Fungus is available upto

3 Kms. Below the earth. Thus the earth is not made for human beings alone.

All these constituents of environment are referred to as the environmental factors or

an ecological factor, which is defined as an ecological condition, which directly or indirectly

affects the life of an organism. These biotic and abiotic components are in a dynamic state

i.e. they constantly depend and affect each other and cannot be dealt in isolation with each

other. This is the fundamental of Environmental Science or Engineering.

Wherever we have not considered this interdependence and interrelation, knowingly

or unknowingly, we have destroyed the very structure of a factor. This unthoughtful

use of a resource, dealt in isolation, pollutes the other environmental factor, which in

turn affects the polluting one, as all of them are interrelated and interdependent. This

is the fundamental of environmental pollution.
