Environment & Biodiversity MCQs

Notes:
Organisms that obtain energy by the oxidation of electron donors in their environments are known as Chemotrophs. These molecules can be both organic (chemoorganotrophs) or inorganic (chemolithotrophs).

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:
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:
The Adaptation Fund was set up to finance the projects and programs aimed at helping developing countries to adapt to the harmful effects of climate change. The Adaptation Fund is supervised and managed by the Adaptation Fund Board (AFB).

Notes:
Tall trees like rosewood, mahogany, kino, teak, dhupa, and hebbalasu grow in Evergreen Forest.

Notes:
Ecotype is the basic unit of Biosystematics. It is adapted to a particular environment but capable of producing fully fertile hybrids with other ecotypes. The term Ecotype proposed by Turesson refers to “an ecological unit to cover the product arising as a result of genotypical response of an ecospecies to a particular habitat.”

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:
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 Keibul Lamjao National Park is a national park in the Bishnupur district of the state of Manipur in India. It is 40 km2 (15.4 sq mi) in area, the only floating park in the world, located in North East India, and an integral part of Loktak Lake. It was created in 1966 as a wildlife sanctuary to preserve the natural habitat of the endangered Eld’s deer. In 1977, it was gazetted as national park.

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.
