Differences between Biodegradable and Non-Biodegradable Pollutants are as follows: Biodegradable Pollutants: i. They are decomposed and degraded by microbes ii. Degradation process is rapid. iii. They are not accumulated but are used up in short time. iv. They are used to produce energy manure, compost and biogas. v. They become part of biogeochemical cycles and give back rapid turn over [...]
The achievement of a measure of stability or homeostasis, rather than a mere increase in productivity, in a fluctuating physical environment may well be the primary purpose of ecological succession when viewed from the evolutionary viewpoint. A mature community with its greater diversity, larger organic structure, and balanced energy flows is often able to buffer the physical environment to a [...]
Integrated control (Stem et.al, 1959) or integrated pest management (IPM) uses biological, chemical and cultural methods of control. This system is ecologically sound because it relies on natural biological control as much as possible and depends on chemical treatments only when absolutely necessary. However, to achieve integrated control, we need to understand the population dynamics of the pest species and [...]
