Environment & Biodiversity MCQs

Notes:
Karnataka lies in Indomalayan biogeographic realm.

Notes:
Micrixalus fuscus (dusky torrent frog or brown tropical frog) is a species of small frog that is found in the dense forested hill streams in the Western Ghats.

Micrixalus saxicola (Malabar tropical frog, black torrent frog, small torrent frog, Jerdon’s olive-brown frog) is a species of frog of the Micrixalidae family and is found in the forest streams in the Western Ghats.

Notes:
The Ghats traverse the States of Kerala, Tamil Nadu, Karnataka, Goa, Maharashtra and Gujarat.
According to the new report by the International Union for Conservation of Nature (IUCN) namely “IUCN World Heritage Outlook 3”, India’s Western Ghats are threatened by population pressure, urbanization and climate change. The site is regarded as of significant concern.

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:
As non-biodegradable wastes like plastic bags, glass bottles, etc., cannot be broken down by decomposers, their disposal poses a big problem. Non-biodegradable wastes can be managed by practicing the concept of 3R— Reduce, Reuse, and Recycle.

Notes:
The most abundant organic compound in the terrestrial environment is cellulose. A type of carbohydrate, cellulose contains chains of glucose rings. Providing strength and rigidity, cellulose forms the cell walls of plants. Cellulose is the primary constituent of wood, making this organic compound the most abundant one on the surface of the Earth.

Notes:
An ecosystem is a community of living organisms in conjunction with other living and nonliving components of their environment, interacting as a system. The nature of the organisms—the species, functional groups and trophic levels to which they belong—dictates the sorts of actions these individuals are capable of carrying out, and the relative efficiency with which they do so.

Notes:
Carbon monoxide inhibits the blood’s ability to carry oxygen to body tissues including vital organs such as the heart and brain. When CO is inhaled, it combines with the oxygen carrying haemoglobin of the blood to form carboxyhemoglobin (COHb). Once combined with the haemoglobin, that haemoglobin is no longer available for transporting oxygen.

Notes:
The greenhouse effect is the process by which radiation from a planet’s atmosphere warms the planet’s surface to a temperature above what it would be without its atmosphere. It caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air.

Notes:
The Gold Panda is the highest conservation award by the World Wide Fund for Nature (WWF), the leading global environmental organisation. WWF is an international non-governmental organization founded in 1961, working in the field of the wilderness preservation, and the reduction of humanity’s footprint on the environment.
