Environment & Biodiversity MCQs

Notes:
Sunhemp is used as Green Manure. Sunhemp as a green manure is needed be ploughed in 2 months after sowing when the plants begin to flower as it decomposes more rapidly and it will have a positive N balance at this stage.

Notes:

Some of the migratory bird species are Siberian cranes, common greenshank, northern pintail, greater flamingo, ruff, black winged stilt, common teal, yellow wagtail, white wagtail, northern shoveller, rosy pelican.

Notes:
Global warming potential (GWP) is defined as the heat absorbed by the greenhouse gas in the atmosphere, as a multiple of the heat that would be absorbed by the same mass of CO2. GWP is 1 for CO2. For other gases it depends on the gas and circumstances.

Notes:
The correct answer is Energy. In a food chain, the transfer of energy is characteristically inefficient – a phenomenon known as the 10% rule, implying that only around 10% of the energy at each trophic level is available for transfer to the next. This invariably leads to a decrease in energy across each level of the food chain. Incidentally, due to this inefficiency of energy transfer, the length of food chains is often restricted, and extensive systems for recycling nutrients and materials exist in ecosystems.

Notes:
A green economy is defined by the employment and income which are driven by the public and private investment into the economic activities, infrastructure and assets that reduced the carbon emissions and control pollution by enhancing energy and resource efficiency, keeping in mind the prevention of the loss of biodiversity and ecosystem services. Green Economy is led by United Nations Environment Programme.
