Conservation of Plants and Animals Online Quiz

In India, protected forests (which include reserved and protected forest categories) cover a significant portion of the total forest area, but the specific figure of 25% is inaccurate as the actual protected area is much higher when considering all categories of forest land under legal protection.

The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources.

Wildlife sanctuaries are protected areas where human activities such as harvesting timber, collecting minor forest products, and private ownership of land are permitted to a limited extent, unlike national parks where such activities are strictly prohibited.

The Dodo was a flightless bird endemic to the island of Mauritius that became extinct in the 17th century due to human activity and invasive species.

Project Tiger was launched by the Government of India in April 1973, not in 2004. Therefore, the statement provided is false.

The Red Data Book is a public document created by the IUCN for recording endangered and rare species of animals, plants, and fungi, as well as some local subspecies that are present within a particular region or country.

Rainfall is essential for maintaining soil moisture and water bodies. A significant reduction in rainfall over a prolonged period leads to water scarcity, which results in drought conditions.

Global warming is primarily caused by the increase in greenhouse gases like carbon dioxide and methane, which trap heat in the atmosphere. Oxygen is not a greenhouse gas and does not contribute to global warming.

Reforestation is the process of planting trees in an area where forests were previously destroyed. This helps to reduce pollution, absorb carbon dioxide, and lower the temperature, making the statement false.

Kaziranga National Park is a famous wildlife sanctuary located in the state of Assam, not Bihar. It is well known for its population of one-horned rhinoceroses.

In protected areas like national parks, sanctuaries, and biosphere reserves, human activities that threaten the ecosystem, such as poaching, hunting, and felling trees, are strictly prohibited to ensure the safety and conservation of wildlife.

Biodiversity refers to the variety and variability of life on Earth, encompassing the different species of plants, animals, and microorganisms, their genes, and the ecosystems they form.

The biosphere is the global ecosystem composed of living organisms (biota) and the nonliving (abiotic) factors from which they derive energy and nutrients. It is the zone of Earth where life exists.

The removal of the top layer of soil, often caused by deforestation or overgrazing, exposes the lower, harder, and less fertile layers, leading to the process known as desertification.

Droughts are extended periods of deficient rainfall that lead to water shortages, crop failure, and environmental stress. This is a direct consequence of reduced precipitation.

Carbon dioxide is a greenhouse gas. An increase in its atmospheric concentration traps more heat, leading to an overall rise in the Earth's average temperature, a phenomenon known as global warming.

Photosynthesis is the biological process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide and water to produce glucose.

During photosynthesis, plants take in carbon dioxide from the atmosphere and water from the soil to produce glucose and release oxygen as a byproduct.

Deforestation removes trees that absorb carbon dioxide and release oxygen, thus causing an imbalance in these gases. Additionally, the loss of forest cover contributes to higher local temperatures, making both (a) and (b) correct.
