This article throws light on the three major priorities for conservation of species in an ecosystem. The three major priorities are: (1) Aims for Conservation, (2) Giving Priority to Particular Species, and (3) In Situ and Ex Situ Conservation. (1) Aims for Conservation: (a) To preserve ecosystem processes e.g. primary productivity, water balance, energy balance, nutrient cycling, slow soil erosion. [...]
Energy has been defined as the capacity to do work. Energy exists in two forms potential and kinetic. Potential energy is the energy at rest {i.e., stored energy) capable of performing work. Kinetic energy is the energy of motion (free energy). It results in work performance at the expense of potential energy. Conversion of potential energy into kinetic energy involves [...]
Pond and lake are fresh water ecosystems in which, like other ecosystems, there are two main components: (A) Abiotic component (B) Biotic component (A) Abiotic component: Abiotic component of pond consists of water, dissolved minerals, oxygen and carbon dioxide. Solar radiations are the main source of energy. (B) Biotic component: It includes the following: (i) Producers (ii) Consumers (iii) Decomposers [...]
