Question 1
1 / -0

The number of zoological parks in India is ____________.

A
$$100$$

B
$$164$$

C
$$124$$

D
$$130$$

Solution

Since the inception of Central Zoo Authority in 1992, the Authority has evaluated 347 zoos, out of which 164 have been recognized.

Hence, 164 is the correct answer.
Question 2
1 / -0

Assertion (A) : The tropical rainforests are mostly evergreen.
Reason (R) : The regions of tropical rainforests get abundant rainfall and have low temperature through the region.

A
Both A and R are true and R explains A.

B
Both A and R are true and R does not explains A.

C
A is true but R is false.

D
A is false but R is true.

Solution

A tropical rainforest occurs roughly within the latitude 28 degrees north or south of the equator (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). These forests experiences high average temperatures and a significant amount of rainfall.
Question 3
1 / -0

Swamps are seen in the Siberian rivers because ________________.

A
Freezing of the river near the mouth prevents water to flow to the sea

B
Rivers are too narrow

C
Rivers are heavily drained by the large network of canals

D
Railway bridges built across the rier obstruct the flow

Solution

Swamps, wetland ecosystem are characterized by mineral soils with poor drainage and by plant life dominated by trees. Swamps are found throughout the world.

They exist in areas with poor drainage and sufficient water supply to keep the ground waterlogged, and they have a high enough supply of minerals in the water to stimulate decay of organisms and prevent the accumulation of organic materials.

They are often found in regions of low relief associated with rivers that supply the water.

Swamps are seen in the Siberian rivers because freezing of the river near the mouth prevents water to flow to the sea.

Hence, option, A is the correct answer.
Question 4
1 / -0

A _____________ is a dense, scrub like vegetation characterized by dry subtropical and temperate areas.

A
Thorn forest

B
Deciduous forest

C
Mountain forest

D
None of these

Solution

A thorny forest is dense, scrub like vegetation characteristic of dry subtropical and warm temperate areas with a seasonal rainfall averaging 250 to 500 mm (9.8 to 19.7 in).
This vegetation covers a large part of southwestern North America and southwestern Africa and smaller areas in Africa, South America, and Australia.
Question 5
1 / -0

Mahagony, ebony and green heart are the trees in _____________.

A
Coniferous forests.

B
Evergreen forests.

C
Monsoon forests.

D
All of these

Solution

In India, evergreen forests are found in the western slopes of the Western Ghats in States such as Kerala and Karnataka. They are also found in hills of Jaintia and Khasi.

Some of the trees found in Indian Tropical Forests are rosewood, mahogany and ebony.

Hence option B is the correct answer.
Question 6
1 / -0

Which one of the following is not essentially a species of the Himalaya vegetation?

A
Juniper

B
Mahogany

C
Silver fir

D
Spruce

Solution

Mahogany is not essentially a species of the Himalaya vegetation. Mahogany is a species of tree found throughout the Caribbean, central and South America not in Himalayas.
Question 7
1 / -0

Which of the following forests are most economical for India?

A
Tropical deciduous

B
Tropical wet evergreen

C
Thorn forests

D
Tidal forests

Solution

As per the economic resource pooling of India, the tropical Deciduous forests are the best ones in terms of export, import and revenue.

These forests have large resources of Sal, Teak, Rosewood and sandalwood trees, which are used for lumbering and also for making multiple products like railway tracks, buildings, furniture and a host of other things. High-quality sandalwood gets exported to the foreign market at a high price.

Hence, option A is the correct answer
Question 8
1 / -0

World's maximum newsprint comes from ______________.

A
Monsoon forest

B
Mangrove forest

C
Deciduous forest

D
Rainfed forest

Solution

Newspapers are made from a type of paper called newsprint. Coniferous softwoods such as spruce, pine, and cedar provide long (average 3mm), strong fibers. Newsprint needs strength enough to withstand the demands of fast printing presses, the ability to accept high-quality color printing and enough opacity to prevent the printing showing through the pages. In most temperate coniferous forests, evergreen conifers predominate, while some are a mix of conifers and broad leaf evergreen trees and/or broad leaf deciduous trees.

Hence, option C is the correct answer.
Question 9
1 / -0

Sundarbans of eastern India is an example of___________.

A
Marine ecosystem

B
Grassland ecosystem

C
Forest ecosystem

D
Mangrove ecosystem

Solution

Mangrove Ecosystem
The name Sundarbans is thought to be derived from sundri or sundari (Heritiera fomes), the name of the large mangrove trees that are most plentiful in the area. The forestland transitions into a low-lying mangrove swamp approaching the coast, which itself consists of sand dunes and mud flats. Mangrove forests constitute about two-fifths of the Sundarbans region’s overall surface area, with water covering roughly half of that area. The landscape is constantly being transformed by the erosional forces of the sea and wind along the coast and by the enormous loads of silt and other sediments that are deposited along the myriad estuaries. Human activity has also altered the landscape, notably through forest removal, which accelerates erosion. In addition, because considerable amounts of river water have been diverted upstream for irrigation and other uses, salinity in the mangrove swamps has moved farther inland, especially in the Indian sector of the territory.
Question 10
1 / -0

Examples of perennial, evergreen and woody plants are.

A
Funaria, Marchantia

B
Marsilea, Horse-tail

C
Cycas-Pinus

D
Ulothrix, Spirogyra

Solution

Perennial, evergreen and woody plants are Cycas, Pinus(gymnosperms).
