Environmental Science In Agricultural MCQ Question and Answer | Agriculture MCQ Question

'Red Data Book' provides data on Threatened species.
The red data book is the document established by the IUCN for documenting the rare and endangered species of plants, animals, fungi and also a few local species that exist within a state or country.
Threatened species are any species (including animals, plants and fungi) that are vulnerable to extinction shortly. This quantitative metric is one method of evaluating the degree of endangerment.

Game fish will be more sensitive to acidity.
Game fish, sport fish or quarry refer to popular fish pursued by recreational anglers and can be freshwater or saltwater fish. Game fish can be eaten after being caught, or released after capture.
The surrounding water has a lower pH, and a fish's cells often come into balance with the seawater by taking in carbonic acid. This changes the pH of the fish's blood, a condition called acidosis.

The geometry of the earth-atmosphere system must determine the climate.
Earth's climate system is a complex system having five interacting components: the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere.
The position of the continents determines the geometry of the oceans and therefore influences patterns of ocean circulation. The locations of the seas are important in controlling the transfer of heat and moisture across the globe, and therefore, in determining global climate.

Man occupies a unique position in the biosphere as they have
A. Large volume of brain - A brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is located in the head, usually close to the sensory organs for senses such as vision.

B. Skilled hand - Someone who is skilled has the knowledge and ability to do something well.

C. Superb memory - It is the ability to have an accurate and detailed recall in a variety of ways, including hyperthymesia, eidetic memory, synesthesia and emotional memory.

Jhuming occurs in India in North East.
The traditional shifting cultivation farming technique of indigenous communities and Bengalis in the Chittagong Hill Tracts in Bangladesh and nearby regions in Arunachal Pradesh, Mizoram and Nagaland in India is known as jhum cultivation.
Jhum cultivation causes extensive damage to the environment. Harmful effects of jhum cultivation include loss of soil fertility, soil erosion, deforestation, destruction of wildlife habitat, and flooding of rivers and lakes.

Biogeochemical cycling refers to cycling of Nutrients in the ecosystem.
A biogeochemical cycle is a pathway by which a chemical substance cycles the biotic and abiotic compartments of Earth.
All the nutrients such as carbon, nitrogen, oxygen, phosphorus and sulphur used in ecosystems by living organisms are part of a closed system; therefore, these chemicals are recycled instead of being lost and replenished constantly such as in an open system.

When food is derived by killing the host, this sort of interaction is Predation.
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation and parasitoidism.
Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell.

The ultimate source of H₂ for biological conservation of solar energy is water.
Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy, and solar architecture.
Warm air containing evaporated water from the oceans rises, causing atmospheric circulation or convection. The latent heat of water condensation amplifies convection, producing atmospheric phenomena such as wind, cyclones and anticyclones.

Soil erosion is more where Rainfall is high.
Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants and animals (including humans).
If the soil is saturated, or if the rainfall rate is greater than the rate at which water can infiltrate into the soil, surface runoff occurs. And if rainfall is high more will be erosion of soil.

Ultra Violet radiations from sunlight cause a reaction that produces O₃.
Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the Earth's atmosphere.
It is present in very low concentrations throughout the latter, with its highest concentration high in the ozone layer of the stratosphere, which absorbs most of the Sun's ultraviolet (UV) radiation.
