Biotic components are the living things that have a direct or indirect influence on other organisms in an environment. For example plants. Abiotic components of an ecosystem include all chemical and physical elements ie. Non - living components.
BOD stands for:
Biological oxygen demand represents the amount of oxygen consumed by bacteria and other microorganisms while they decompose organic matter under aerobic conditions at a specified temperature.

Development with both intragenerational and intergenerational quality is called:
Intergenerational equity is the concept or idea of fairness or justice between generations.
Intra- generational equity is concerned with equity between people of the same generation and aims to assure justice among human beings that are alive today.
We can define Sustainable development as development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
Intergenerational and intra- generational equity are the underlying principles of sustainable development as:
Intergenerational equity tends to a fair utilization of resources by human generations in past, present and future, it tries to construct a balance of consumption of resources by existing societies and future generations.
Intra-generational equity makes sure that the resources which are not preserved for the future generation and are available for the current generation must be equally distributed among all the members of the present generation.
Sustainable consumption can be achieved by:
The 3R approach, focusing on reduce, reuse, and recycle, essentially aims to set up a sound material cycle society within the concept of a life-cycle economy, where consumption of natural resources is minimized and the environmental load is reduced, as much as possible.
Joint forest management is an example of :
Chipko movement was led by :
Which form of coal is hardest and with maximum carbon content ?

The quality of environment can be improved by
Maximum petroleum is used in
The isomeric pair is
Butane and 2-methyl propane is an isomeric pair as both consist of 4 atoms of carbon and 10 atoms of hydrogen. They have the same molecular formula i.e C4H10.
Ecological imbalance in the biosphere is created by
Human activities are responsible for the disturbance of the balanced system of environment. Increasing human population is a major reason for cutting of trees. Vast tracts of forest had been cleared to make way for farmland and for making new houses, factories and infrastructure.
Production of more paper is also responsible for depletion of forest cover. Around 4 billion trees worldwide are cut down for paper every year.
Floods can be prevented by

One of the world’s most critical watersheds are found in
The Greater Himalayan Watershed is a vast and diverse area that stretches from Uzbekistan to Myanmar. The Hindu Kush and Himalayan mountain ranges contain over 50,000 glaciers, the melt water of which feeds the aquifers and water tables of ten of the world’s most important river systems. The Amu Darya, Brahmaputra, Ganges, Yellow, and Indus rivers – all crossing international borders – are just some of the important systems that depend on the regular cycles of glacial freezing and melting in order to maintain their seasonal water levels.
They act as a shield separating the Indian subcontinent from the Arctic winds that batter Central Asia. They also trap the hot, moist air in the Southeast and enable the torrential monsoons that occur during the summer months, accounting for 75% of India’s annual rainfall.
Khadin system of water harvesting is found in
The 'Khadin' system of rainwater harvesting was practiced in ancient times in Rajasthan. In this system, a very long (about 100 m - 300 m long) earthen embankment called 'Bund' is built across the lower hill slopes lying below gravelly uplands. The rainwater from the catchment area is made to flow down the slopes and stopped by the 'Bund' to form a reservoir. The rainwater collected in the reservoir formed by the 'Bund', and in the well, gradually penetrates into the land (or ground). This water - saturated land is subsequently used for growing crops. In this way, rain water harvesting was done using khadin system in Rajasthan.
