Environment & Biodiversity MCQs

Notes:
Indian Network on Climate Change Assessment consists of over 120 institutions and over 250 scientists country wide. It carries out research on the effects of climate change in different regions and sectors in India and also suggests suitable adaptation and mitigation strategies.

Notes:
The branches of sustainability include the environment, the needs of present and future generations and the economy. Sustainable development is the type of development that meets the needs of the present generations without compromising the ability of future generations to meet their own needs.

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:
Impact prediction in EIA is a method of mapping the environmental impacts of the significant aspects of the project and its alternatives. Environmental impact can never be predicted with absolute certainty.

Notes:
Carbon Diet refers to reducing the impact on climate change by reducing greenhouse gas production especially CO2 , without lowering their standard of living. A low-carbon diet involves making lifestyle choices related to food consumption which reduce resulting greenhouse gas emissions (GHGe).

Notes:
Nanotoxicology is defined as the study of the toxicity of nanomaterials. nanomaterials have unique properties as compared to their larger counterparts because of the large surface area to volume ratio of nanomaterials. Inhalation exposure is of most concern because of its quantum size.

Notes:
Namami Gange mission is run by the Central
Government in five states namely
Uttarakhand, Uttar Pradesh, Jharkhand,
Bihar and West Bengal. It is managed by West Bengal Forest Department for
sustaining the biodiversity of the Ganga river ecosystem along with its
purification.

Notes:
Chlorofluorocarbons (CFCs) are nontoxic, non-flammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants. Because CFCs contribute to?ozone?depletion in the upper atmosphere, the manufacture of such compounds has been phased out under the Montreal Protocol.

Notes:
Plants and animals interact with each other in the environment. In the food chain, some animals each other animals and use them for food. Some animals depend on others through symbiotic relationships. Plants provide a global benefit to animals by releasing oxygen into the atmosphere.

Notes:
In ecology, abiotic components are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Abiotic components include water, light, radiation, temperature, humidity, atmosphere, and soil.
