The importance of ecology is due to the presence of man in the ecosystem. Man interacts not only with its own species but also with other living organisms.
There are millions and millions of organisms in dynamic co-existence with each other and each one of them plays a significant role in the eco-system.
Ecology thus, has broad objective and provides a scientific basis for the aims of environmentalism, as well as for evaluating its goals and policies.
Ecology does not dictate what is 'right' or 'wrong' but provides knowledge about the quantification of biodiversity and population dynamics.
The objective of ecology is to understand the dynamics of our surroundings and to take proper measures to conserve it if and when required. However, the main objective of ecology is to study:
1. The local and geographical distribution and abundance of organisms.
2. The inter-relationship between organisms in population and communities.
3. The structural adaptations and functional adjustments of organisms to their physical environment.
4. The behaviour of organisms 'under natural conditions.
5. The biological productivity of nature and its relationship with mankind.
6. Temporal changes in the occurrence, abundance and activities of organisms.
7. Conservation and management of natural resources and pollution.
