Environment & Biodiversity MCQs

Notes:
The National Biodiversity Authority also called as NBA is a statutory autonomous body, under the Ministry of Environment and Forests, Government of India. It was established in 2003 and headquartered in Chennai.

Notes:
The Paris Agreement aimed to hold the increase in global average temperature to well below 2 °C above pre industrial levels. Efforts were to be aimed to limit temperature increase to 1.5°C above pre-industrial levels.

Notes:
The Screening Criteria under Environment Impact Assessment are based upon the following:
1. Scales of investment
2. Type of development
3. Location of development

Notes:
Gene banks are established to protect genetic material, be it plant or animal. In plants, genetic material can be saved by freezing cuts from the plant, or stocking the seeds. In animals, genetic material can be saved by freezing of sperm and eggs in zoological freezers until further need.

Notes:
Xerosere is a type of plant succession which is limited by water availability. Xerosere originates on rock surfaces which are in an unweathered state. There are different stages in a xerarch succession.

Notes:
Sholas are the local name for patches of stunted tropical montane forest found in valleys amid rolling grassland in the higher montane regions of South India.

Notes:
Use of chemical fertilisers and excessive use of chemical pesticides are primarily responsible for pollution of our water and land resources. Manure and pesticides contains nutrients, such as phosphorus and nitrogen, and pathogens, including bacteria, viruses and parasites. These pollutants contaminate water resources and reduce recreational potential of lakes and rivers, destroy wildlife habitat, and eliminate drinking water supplies for people and livestock.

Notes:
Primary producers are the organisms in an ecosystem that produce biomass from inorganic compounds (autotrophs). In almost all cases, these are photosynthetically active organisms (plants, cyanobacteria and a number of other unicellular organism.

Notes:
Chitwan National Park in Nepal is contiguous to the Indian Tiger Reserve Valmiki National Park. Adjacent to the east of Chitwan National Park is Parsa National Park. The coherent protected area of 2,075 km2 represents the Tiger Conservation Unit (TCU) Chitwan-Parsa-Valmiki, which covers an area of 3,549 km2.

Notes:
Mylo is a leather-like material made from mycelium, the underground root structure of mushrooms. Mylo is a sustainable alternative to leather because it can be grown without polluting substances. It is also more sustainable than synthetic leathers, which are usually made from petroleum-derived inputs.
Mylo is grown in a controlled indoor environment. The growing process is designed to be low impact and takes less than two weeks. It emits fewer greenhouse gases and uses less water and resources than animal-based leather.
Mylo is 80% bio-based and is completely biodegradable and compostable. However, when extra durability is needed, the mushroom leather is reinforced with polyurethane, which decreases its biodegradability.
