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

An ecological pyramid of energy flow is, often an inverted pyramid in the Ocean ecosystem.
Life on the ocean's surface connects worlds. From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there.
In this ecosystem, the standing crop of phytoplankton, the major producers, at any given point will be lower than the mass of the heterotrophs, such as fish and insects. This is explained as the phytoplankton reproduce very quickly, but have much shorter individual lives.

Adherence to the two-children norm shall help in Stabilising ecosystem. An ecosystem is said to possess ecological stability or equilibrium if it is capable of returning to its equilibrium state after a perturbation or does not experience unexpected large changes in its characteristics across time.
Focusing on the biotic components of an ecosystem, a population or a community possesses numerical stability if the number of individuals is constant or resilient. Adhering to two children will maintain the ratio of population with the availability of resources.

The method for converting combustible gaseous compounds CO₂ and H₂O, halogen HX and S to SO₂, is Adsorption method.
Adsorption is a surface phenomenon and does not penetrate through the surface to the bulk of the adsorbent, while absorption involves the whole volume of the material, although adsorption does often precede absorption. It is the adhesion of atoms, ions, or molecules from a gas, liquid or dissolved solid to a surface.

Dudhwa National Park is located in Uttar Pradesh.
The Dudhwa National Park is a national park in the Terai belt of marshy grasslands in northern Uttar Pradesh, India.
It stretches over an area of 490.3 km², with a buffer zone of 190 km². It is part of the Dudhwa Tiger Reserve in the Kheri and Lakhimpur districts.
The park is located on the Indo-Nepali border in the Lakhimpur Kheri District and has buffers of reserved forest areas on the northern and southern sides.

Hypothesis is Hunch of scholars.
A hypothesis is a proposed explanation for a phenomenon. The words "hypothesis" and "theory" are often used interchangeably, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research in a process beginning with an educated guess or thought.
Hunch is also a thought or an idea that is based on a feeling rather than on facts or information, and hyphothesis can be referred to as hunch of Scholar or researcher.

Chlorella has maximum efficiency to convert solar energy into chemical energy.
Chlorella is a genus of about thirteen species of single-celled green algae of the division Chlorophyta.
Their chloroplasts contain the green photosynthetic pigments chlorophyll-a and -b. In ideal conditions cells of Chlorella multiply rapidly, requiring only carbon dioxide, water, sunlight, and a small number of minerals to reproduce.
Chlorella could convert 20% of solar energy into a plant that, when dried, contains 50% protein.

Major health effects due to depletion of ozone layer are Increase in eye cataracts and mutation, Increase in skin cancer and melanoma and also a decrease in growth of ocean flora and fauna.
Ozone layer depletion increases surface UVB levels, which could lead to damage, including an increase in skin cancer. The ozone hole was seen as a "hot issue" and imminent risk as laypeople feared severe personal consequences such as skin cancer, cataracts, damage to plants, and reduction of plankton populations in the ocean's photic zone.

Man has created his special environment. It is called a Noosphere.
The word is derived from the Greek Noo word means "mind", "reason" and "sphere", in lexical analogy to "atmosphere" and "biosphere".
The noosphere shares the common thesis that together human reason and scientific thought have created, and will continue to create, the next evolutionary geological layer. This geological layer is part of the evolutionary chain.

The Earth's capital are Air, water and soil, Wildlife, raw materials and minerals, and Energy resources and degradation.
The earth's capital includes organisms, plants and animals that have resources like air, water, land, soil for come and gone, but some have stayed.

O₃ produces another air pollutant by reacting with oxides of nitrogen in presence of sunlight.
High levels of nitrogen dioxide are also harmful to vegetation damaging foliage, decreasing growth or reducing crop yields. Nitrogen dioxide can fade and discolour furnishings and fabrics, reduce visibility, and react with surfaces.
In the sunlight, oxygen reacts with nitrogen oxides emitted mainly from vehicles, power plants, and industrial activities to form ozone, which in turn helps the formation of organic aerosol.
