Environment & Biodiversity MCQs

Notes:
The mitigation and compensation measures for all the identified significant impacts should be and financial plan for implementing the mitigation measures should be delineated under Environment Management Plan.

Notes:
The intentional release or dissemination of biological agents is known as Bio-terrorism. These agents of bio-terrorism  include bacteria, viruses, or toxins, and may be in a naturally occurring or a human-modified form.

Notes:
BioWeb is a network of web-enabled biological devices which expands an internet of things to the Internet of Living Things of natural sensory devices. These devices provide insights to real-time ecological data and feedback to changes in the environment.

Notes:
The species commonly found in Sub-alpine Forests are junipers, birch, rhododendrons,
berberis, maling bamboo, laurel, etc. Oak and magnolia occur around the region of
Kalimpong. In the upper Singalila range, dwarf rhododendrons, meadows and
small flowering bushes occur.

Notes:
Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from drinking water. It can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water (Desalination of marine water). It is most commonly known for its use in drinking water purification plants particularly in countries of middle east.

Notes:
Green House Effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric green house gases and is re-radiated in all directions. It results an increase in average temp of the planet.

Notes:
According to the US Environmental Protection Agency (EPA), automobile emissions are the number one source of carbon monoxide, lead, nitrogen oxides, and volatile organic compounds released into the atmosphere that are primarily responsible for air pollution. Industrial processes are the number two cause of lead pollution in the air, following automobile emissions.

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 Great Dividing Range, home to a UNESCO World Heritage Site – the Wet Tropics of Queensland, exhibits an exceptional display of natural beauty, diverse species, and is soaked in evolutionary history. This region preserves the ancient Gondwanan forest of 50-100 million years ago, and is significant in deciphering the evolution of Australian flora and fauna. The range hosts over 400 threatened or rare species and indigenous communities have resided here for over 5,000 years. The highest Australian waterfall, Wallaman Falls, the 13 primary river systems, and multiple national parks are also part of this geography.
