Environmental Science

Soil chemistry is considered an edaphic factor.

Trichoderma harzianum has proved a useful microorganism for bioremediation of contaminated soils.

Biomagnification, also known as bioamplification or biological magnification, is any concentration of a toxin, such as pesticides, in the tissues of tolerant organisms at successively higher levels in a food chain.

Food webs consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems.

BOD stands for Biological Oxygen Demand. It is the amount of dissolved oxygen required by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period.

Biotic potential is defined as the physiological capacity of organisms to produce their offspring under natural conditions. It is also called reproductive potential. In nature, the biotic potential of organisms is enormous but all the organisms do not survive due to the lack of food and space.

If the Earth had no atmosphere then the sky would have looked dark. The original colour of the sky(or space) is black. Just the atmosphere of the Earth gives the colour white, blue and dark blue.

Ecology is the scientific study of the interaction of organisms with each other and the environment.

Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Incineration and other high-temperature waste treatment systems are described as “thermal treatment”. Incineration of waste materials converts the waste into ash, flue gas and heat.
