Environment & Biodiversity MCQs

Notes:
The Disaster Management Act, 2005 received the Presidential assent on 23 December, 2005. It envisaged the creation of the National Disaster Management Authority with not more than nine members (including a Vice-Chairperson) and the Prime Minister of India as its chairperson.

Notes:
Silent Valley National Park is located in the state of Kerala and is located in the Nilgiri hills. It is home to the lion-tailed macaques, an endangered species of primate. In 1973, “Save Silent Valley” campaign (environmental movement) was initiated when the Kerala State Electricity Board declared to implement the Silent Valley Hydro-Electric Project.

Notes:

Notes:
Aanaimalai Tiger Reserve was also known as Indira Gandhi Wildlife Sanctuary and National Park is located in the state of Tamil Nadu. The practice of sliding timber logs down the hills from a place located in the northeast corner of the park is named as “Topslip”. It is a famous tourist attraction.

Notes:
Silent Valley National Park also known as “Sairandhri Vanam” is located in the state of Kerala and is located in the Nilgiri hills.

In 1973, “Save Silent Valley” campaign (environmental movement) was initiated when the Kerala State Electricity Board declared to implement the Silent Valley Hydro-Electric Project.

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:
Bioversity International, a non-profit research organization for development, was established in 1974. The motto of the organization is “Agricultural biodiversity nourishes and sustains the planet”. It is headquatered at Rome, Italy.

Notes:
This feedback loop, known as the ‘ice-albedo feedback’, amplifies the initial warming caused by rising levels of greenhouse gases. Detecting, understanding and accurately quantifying climate feedbacks have been the focus of a great deal of research by scientists unraveling the complexities of Earth’s climate.

Notes:
A pioneer community is a collection of organisms able to colonize bare rock. Lichens help break down rock and accumulate debris, helping to form a thin soil layer. The soil layer begins to support small forms of life.
