Energy Transformation Through Primary Productivity and Nutrient Dynamics of Lentic Water

Abstract

Some societies can cope, at least temporarily, with pollution and availability constraints. In most of the world, however, population increases continue without significant reduction rates. Growth will continue to impose increasing demands upon freshwater supplies. Control and reversal of degradation requires a proper economic and social valuation of fresh water. Human impact on freshwater ecosystems will increase until industrial growth is stabilized.

Emotionalism and alarmist reactions to the momentum of exploitation by the technological system accomplish little. Understanding the metabolic responses of aquatic ecosystems is essential in order to confront and offset the effects of human alterations. Many small ponds in different parts of the world have been drained or reclaimed to extend arable land. This has caused unusual fluctuations in water land, the impact of which is tremendous. The biodiversity and dynamics of different phytoplankton population are one of the least explored areas in aquatic biology.

Ecological studies give humans a deep insight into principles of life, its forms and levels of existence. F.A forel may be considered as the founder of modern limnology for his original work on Swiss Lakes. The primary social need of every sustainable society is to protect and utilize all their natural resources wisely.

In India, such studies on the pattern of energy flow in aquatic ecosystem by various organisms at different trophic levels are very few. Odum suggested to bring out a comparative picture by investigating the physical, chemical and biological characteristic of lentic water bodies. It is clear that no detailed bioecological investigations have been done so far in this area.
