INTRODUCTION
Before you start reading this topic, just look around and note the various
things that surround you like clouds, paper, chair, friends, etc. It is impossible to
be alone in this earth, isn’t it? After all, no man is an island!
There are a lot of definitions for the word environment in the literal and
scientific contexts, but the most acceptable definitions can be given as below.
The first one is my choice.
3) Environment is the sum total of all living and non living factors that
compose the surroundings of man
The word environment is derived from the French word “environ”. The
meaning of the French word is somewhat related to “encompass” “encircle” etc. It
is believed to have been introduced into the subject by biologist Jacob Van Erkul
in the early 1900s.
With environment being such a generalized term, its classification and an
understanding of its composition becomes a necessity.
CLASSIFICATION OF ENVIRONMENT
The classification of the environment can be best described from the following
figure
Atmosphere
PHYSICAL Hydrosphere
ENVIRONMENT
Lithosphere
Floral
ENVIRONMENT BIOLOGICAL
ENVIRONMENT Faunal
Microbia
l
Society
CULTURAL
ENVIRONMENT Economy
Politics
Off these, we are more concerned with the physical environment from our
perspective as the cultural environment and biological environment are left to
specialists like economists and biologists. Read further for a brief intro of the
cultural and biological environments.
The Cultural Environment gives an idea of learned behavioral traits those are
clear and shared by members of society. For example, if a person born in India
and living in India and a person born in India and living in Australia would have
two different cultural environments, which they have to adapt too. The students
may have already come across the problems of cross cultural communication,
which is indeed related to the cultural environment of an organism. The cultural
environment can be divided into three sub-heads namely
The social environment reflects the traditions that he or she was grown, lives in,
and the community with whom the individual interacts. The economic
environment refers to the set of factors that surrounds the organism involving
monetary, natural, and human resources that influence the behavior of that
particular organism. The political environment involves the environment involving
conflicting interactions, between other organisms, often resulting in the formation
of alliances or coalitions and used to resolve the conflict and achieve the goals of
the allies or their influential members. The most important thing about the
cultural environment is that it cannot be physically represented, but it is
there anyway. The study of this aspect of environment is taken care by
economists, sociologists, politicians and other such people.
The biological environment as the name indicates refers to the various flora
(plants), fauna (animals) and microbes (micro organisms) that are found in our
surroundings. We are already familiar with this environment through our study of
biological sciences.
COMPONENTS OF ENVIRONMENT
Here the components are classified in terms of biotic and abiotic based upon
life. The biotic components are further listed as producers, consumers and
decomposers and the abiotic components are classified as climatic(water, air)
and edaphic(land). It is from this component system that the study of structure
of ecosystem was evolved.
COMPONENTS
CLIMATIC EDAPHIC
PRODUCERS CONSUMERS DECOMPOSERS
1. Hydrosphere(Water)
2. Atmosphere(Air)
3. Lithosphere(Land)
4. Biosphere(Flora/Fauna/Microbes)
5. Anthrosphere (man made things)
I understand your confusion on what to write if they ask you the components
of environment. It is pretty simple logic. If they ask biotic and abiotic
components, follow the British way. If they ask about the spheres of
environment, be American. If they simply ask components of environment,
show that you are an Indian by plainly writing down air, land and water.
ENVIRONMENT, ECOLOGY AND ECOSYSTEM
Environment, Ecology and Ecosystem are three different terms. But they are
inter related.
Ecology is a branch of study of the interrelationships with the organism and its
environment. It is a basic fact that the Earth includes a tremendous variety of
living things which depend in some way on other living and nonliving things in
its Environment. Definitely, as an organism, camel has a relationship with its
environment. Humans have a working relationship with cows, chickens, bees
etc. This study of how the existence and activity of organism influences its
environment and the vice versa is ecology. Ecology comes from the Greek
Words OIKOS (house or place where one lives) and LOGOS (study of) and
was formed by Ernst Haeckl in 1869. Thus Ecology means house study or
Study of the “House” (the scientist referred the earth as house in all his
works) in which we Live. Ecology involves collecting information about
organisms and their environment, looking for patterns, and seeking to explain
these patterns. It can be confidently established that Environmental Science
is more or less Ecology.
The ecology that takes place in a defined area is called ecosystem. Say your
relation with water, light, humans, dogs etc in a city, or in a forest, sea etc.
Ecosystem is a functional unit of dynamic system of organisms interacting
with each other (biotic) and the inanimate environment (abiotic). We will be
looking more into the concept of ecosystems in the future topics.
