What is Ecology?
Ecology is the study of the distribution and abundance of
organisms, the interaction between organisms, the interaction between organisms
and their environment, and structure and function of ecosystems.
The ecology serves the purpose to provide knowledge about
the way the world works and provide evidence on the interdependence between the
natural world and people. A better understanding of ecological systems will
allow society to predict the consequences of human activity on the environment.
The environment in which the man and other organisms live is
called the biosphere. The biosphere is made up of different regions that have
different types of flora (plants) and fauna (animals). The types of organisms
in an area are determined by various factors such as the climate, temperature,
Environmental pollution – The environmental pollution is any
discharge of material or energy into water, land, or air that causes or may cause
acute (short-term) or chronic (long-term) detriment to the Earth's ecological
balance or that lowers the quality of life. Pollutants may cause primary
damage, with direct identifiable impact on the environment, or secondary damage
in the form of minor perturbations in the delicate balance of the biological
food web that are detectable only over long time periods.
Biodiversity is the variety and differences among living organisms from all
sources, including terrestrial, marine, and other aquatic ecosystems and the
ecological complexes of which they are a part. This includes genetic diversity
within and between species and of ecosystems. In other words we can say biodiversity
represents all life.
one of the mega biodiversity centres in the world and has two of the world's 18
‘biodiversity hotspots’ located in the Western Ghats and in the Eastern Himalayas (Myers 1999). The forest cover in these
areas is very dense and diverse and of pristine beauty, and incredible
According to a
Ministry of Environment and Forest Report (1996) of Government of India, the
country is estimated to have over 45,000 plant species and 81,000 animal
species representing 7% of the world’s flora and 6.5% of its fauna. The 1999
figures are 49,219 plant species representing 12.5% and 81,251 animal species
Green House Effect-
The greenhouse effect is a process by which thermal radiation from a planetary
surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all
directions. Since part of this re-radiation is back towards the surface and the
lower atmosphere, it results in an elevation of the average surface temperature
above what it would be in the absence of the gases.
