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

Organisms of an ecosystem are linked together in Food chains.
A food chain is a linear network of links in a food web starting from producer organisms (such as grass or algae which produce their food via photosynthesis) and ending at an apex predator species (like grizzly bears or killer whales), detritivores (like earthworms or woodlice), or decomposer species (such as fungi or bacteria).
A food chain also shows how organisms are related to each other by the food they eat. Natural interconnections between food chains make it a food web.

The water (hydrologic cycle) is driven by solar energy and gravity.
The water cycle, also known as the hydrologic cycle or the hydrological cycle, is a biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth.
The water cycle is powered by the energy emitted by the sun. This energy heats water in the ocean and seas. Water flows vertically through the soil and rocks under the influence of gravity.

The maximum water vapour held in the atmosphere is Saturation point.
The water-vapour content of the atmosphere varies from place to place and from time to time because the humidity capacity of air is determined by temperature.
At 30°C (86°F), for example, a volume of air can contain up to 4% water vapour. At -40°C (-40°F), however, it can hold no more than 0.2%.

Throwaway societies are Today's advanced industrialized countries, Today's most polluting countries or Asia and Australia.
The throw-away society is a generalized description of human social concept strongly influenced by consumerism, whereby the society tends to use items once only, from disposable packaging, and consumer products are not designed for reuse or lifetime use.

Plants requiring low calcium amount or found in acidic soil is Oxylophytes.
Plants growing in soils that have a rich amount of, acidic nature and a lack of ions are called oxylophytes and these are the plants that grow in acidic soil kept at pH 5.5 as this allows the plant to absorb nutrients required for growth.

Phosphorus and Sulphur is a sedimentary type of biogeochemical cycle.
Sedimentary cycles are a type of biogeochemical cycle, in which the reservoir is Earth's crust. Sedimentary cycles include those of iron, calcium, phosphorus, sulphur, and other more-earthbound elements.
The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere and biosphere.
The sulphur cycle is a biogeochemical cycle in which the sulphur moves between rocks, waterways and living systems.

Fertilizers obtained from sea birds along with coast of Chile and Peru are Guano.
Guano is the accumulated excrement of seabirds or bats. Guano is a highly effective fertilizer due to its high content of nitrogen, phosphate, and potassium, all key nutrients essential for plant growth.
Archaeological evidence suggests that Andean people collected seabird guano from small islands and points off the desert coast of Peru for use as a soil amendment.

Environmental historians are Paul Ehrlich, Donella H. Meadows and Rachel Carson.
Paul Ralph Ehrlich is an American biologist best known for his pessimistic and wildly inaccurate predictions and warnings about the consequences of population growth and limited resources.
Donella Hager "Dana" Meadows was an American environmental scientist, educator, and writer. She is best known as lead author of the books The Limits to Growth and Thinking in Systems: A Primer.
Rachel Louise Carson was an American marine biologist, writer, and conservationist whose influential book Silent Spring and other writings are credited with advancing the global environmental movement.

Maximum control of hydrological cycle is exerted by Forests.
The water cycle, also known as the hydrologic cycle or the hydrological cycle, is a biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth.
The source of energy for evaporation is primarily solar radiation. Evaporation often implicitly includes transpiration from plants, though together they are specifically referred to as evapotranspiration.

The characteristics of a community are Diversity, Periodicity and Dominance.
In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage.
It is the study of the interactions between species in communities on many spatial and temporal scales, including the distribution, structure, abundance, demography, and interactions between coexisting populations.
