Q) A very large ecosystem on land having distinct type of vegetation and wildlife is called?

[1] Biome

[2] Biodiversity

[3] Biosphere reserve.

[4] Ecology

[5] none of these.

[Explanation] A biome is a community of plants and animals that have common characteristics for the environment they exist in. They can be found over a range of continents. Biomes are distinct biological communities that have formed in response to a shared physical climate. “Biome” is a broader term than “habitat”; any biome can comprise a variety of habitats.

Q) India’s first micro forest will be built in which state?
[1] Madhya Pradesh
[2] West Bengal
[3] Uttar Pradesh
[4] Chhattisgarh
[5] Maharashtra

[Explanation]
India’s first micro forest will be built in Raipur, Chhattisgarh. Approximately, 19 acres of land which housed around 70 government office buildings will be converted into micro forest in order to create an oxy-zone. The micro forest will provide fresh air to Raipur which is the 7th most polluted city in the world. It will reportedly be open to the public in the next 8 months.

Q) Which of the following actions have to be avoided to prevent the depletion of DO (dissolved oxygen) in aquaculture?
[1] Over-aerating, over-warming, over-harvesting
[2] Over-seining, over-planting, over-medicating
[3] Over-feeding, over-stocking, over-fertilizing
[4] None of these
[5] All of the above

[Explanation]
Over-fertilizing causes organic pollution, Over-stocking causes competition for DO and nutrients, Over-feeding causes pollution and bacterial growth. So, these 3 actions must be avoided in aquaculture.

Q) “It refers specifically to a particular cemented horizon in certain soils which when dried, become very hard, like a brick”.Which specific process is mentioned here?
[1] Lateralization
[2] Horizonation
[3] Gleization
[4] Salinization
[5] None of the above

[Explanation]
It refers specifically to a particular cemented horizon in certain soils which when dried, become very hard, like a brick. Such soils (in tropics) when massively impregnated with sesquioxides (iron and aluminium oxides) to extent of 70 to 80 per cent of the total mass, are called laterites or latosols (Oxisols). The soil
forming process is called Laterization or Latozation. Laterization is the process that removes silica, insteadof sesquioxides from the upper layers and thereby leaving sesquioxides to concentrate in the solum.

Q) What is the pressure required to operate Hand Compression sprayer?
[1] 2.0 – 3.5 kg/cm2
[2] 3.0 – 4.5 kg/cm3
[3] 2.5 – 3.5 kg/cm4
[4] 4 – 4.5 kg/cm5
[5] None of the above

[Explanation]
HAND COMPRESSION SPRAYER: It is suitable for applying chemicals for field crops and lawns. The pump is operated to pump air in to the tank to build pressure up to 2.0 – 3.5 kg/cm2. When the flow cut off lever ispressed, the fluid passes through the nozzle and spraying is done. The sprayer is carried on the shoulder
of the operator. The application rate ranges from 45 to 100 liters /ha.

Q) What is the field capacity of an Indigenous Plough?
[1] 0.4 ha per day of 8 hours
[2] 0.6 ha per day of 8 hours
[3] 0.8 ha per day of 8 hours
[4] 0.2 ha per day of 8 hours
[5] None of the above

[Explanation]
Indigenous Plough- INDIGENOUS PLOUGH It is an animal drawn plough. It penetrates into the soil and breaks it open. It forms V shaped furrows with 15-20 cm top width and 12-15 cm depth. It can be used for ploughing in dry land, garden land and wetlands. The size of the plough is represented by the width of the
body and the field capacity is around 0.4 ha per day of 8 hours.

Q) Which of the following have a three-dimensional framework of silicate tetrahedra with SiO2 or a 1:2 ratio. This is the largest mineral group comprising nearly 75% of the crust of the Earth.
[1] Ortho silicate
[2] Neo Silicate
[3] Phyllosilicate
[4] Sheet silicate
[5] Tectosilicate

[Explanation]
Tectosilicates are framework silicates which have a three-dimensional framework of silicate tetrahedra with SiO2 or a 1:2 ratio. This is the largest mineral group comprising nearly 75% of the crust of the Earth.

Q) Isinglass is made from?
[1] Shark fins
[2] Fish maws
[3] Prawn shell
[4] Chitin
[5] all of the above.

[Explanation]
Fish maws are served in soups or stews and also used as a source of collagen. They can be made into strong, water-resistant glue, or used to make isinglass used in clearing up beer and wine during
manufacturing.

Q) Practice of forestry with the object of raising flowering trees and shrubs mainly to serve as recreation forests for the urban and rural population, is known as?
[1] Recreation forestry
[2] Extension forestry
[3] Farm forestry
[4] Mixed forestry
[5] all of the above.

[Explanation]
Farm Forestry: Farm forestry is the name given to programmes which promote commercial tree growing by farmers on their own land. Farm forestry was defined by NCA (1976) as the practice of forestry in all its aspects in and the around the farms or village lands integrated with other farm operations.
Extension Forestry: It is the practice of forestry in areas devoid of tree growth and other vegetation situated in places away from the conventional forest areas with the object of increasing the area under tree growth.
Recreation Forestry: It is the practice of forestry with the object of raising flowering trees and shrubs mainly to serve as recreation forests for the urban and rural population. This type of forestry is also known as Aesthetic forestry which is defined as the practice of forestry with the object of developing or maintaining a forest of high scenic value.

Q) The felling made in an immature stand for the purpose of improving the growth and form of tree is termed as?
[1] Heading back
[2] Punning
[3] Thinning
[4] Coppicing
[5] all of the above.

[Explanation]
In forestry, thinning is be done to make the stand more profitable in an upcoming final felling or to achieve ecological goals such as increasing biodiversity or accelerating the development of desired structural attributes such as large diameter trees with long tree crown. Thinning may be done to increase the
resistance of the stand to environmental stress such as drought, insect infestation, extreme temperature, or wildfire.
