Environment & Biodiversity MCQs

Notes:
National Initiative On Climate Resilient Agriculture was launched by the Indian Council of Agricultural Research with funding from the Ministry of Agriculture, Government of India. It was launched in February 2011.

Notes:
The Focus of an earthquake, which is also called as a Hypocenter is the point of the origin of an earthquake whereas the epicenter is the point just exactly above the focus.

Notes:
The lakes which have low primary productivity as a result of low nutrient content are known as Oligotrophic Lake. These lakes have very low algal production therefore they often have very clear waters, with high drinking-water quality.

Notes:
Karnataka lies in Indomalayan biogeographic realm.

Notes:
Sundarbans Tiger Reserve is one of the initial nine tiger reserves constituted at the time of
inception of the Project Tiger Scheme in the year 1973.

Notes:
An Air Quality Index (AQI) of 301-500 is considered as hazardous to human health. It denotes the severely polluted state of air. AQI values over 300 trigger health warnings of emergency conditions. The entire population is even more likely to be affected by serious health effects.

Notes:
Lichens are actually two types of organisms living together, a fungus and an alga. The fungus makes the body that protects the alga and the alga provides the food for the fungus. Lichens can be used as air pollution indicators, especially of the concentration of Sulphur dioxide in the atmosphere.

Notes:
Lichens are found in both nature and in human-made environments, including rocks, trees, barren earth, metal and concrete. They are sensitive to air pollution because they receive all nutrients from the atmosphere, which makes them valuable as indicator species. The presence of sulphur dioxide force them to perish.

Notes:
Sikkim is the largest producer of orchids in India. The state is home to an amazing 450 species of exotic orchids alone. Annually, around 20 million stalks of orchids are produced in Sikkim. Sikkim, owing to its climatic conditions, has developed as a natural hub of orchids.

Notes:
The Pantanal Conservation Area, recognized as a UNESCO World Heritage Site, accounts for 1.3% of the vast Pantanal wetland in Brazil and spans across 187,818 hectares. It provides shelter for more than 650 bird species, 325 fish species, and 80 mammal species, including giant armadillo and jaguar. The area’s unique ecosystem extends from floodplains to the Amolar Mountains, supporting diverse habitats and maintaining regional fish stocks. Moreover, it is an all-important breeding ground for wetland birds and refuge for globally threatened species like the hyacinth macaw. Additionally, it is a Ramsar Wetland and a UNESCO Man & Biosphere Reserve.
