Question 1
1 / -0

Number of protected areas around the world is

A
17000

B
37000

C
1700

D
3700

Solution

Protected areas, also known as the conservation areas are places which receive some protection due to their recognized natural, ecological or cultural values. There are many kinds of such areas, which vary by their respective level of protection. The level of protection depends on the enabling laws of each country or the regulations of the international organizations involved. Around the world, the number of such areas is 37,000.
So, the correct answer is '37000'.
Question 2
1 / -0

Number of national parks currently operating in India is

A
67

B
78

C
166

D
108

Solution

A park in use for conservation purposes is known as a National park. It is basically a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Currently, in India we have 166 national parks. Only 5 were there in 1970.
So, the correct answer is '166'.
Question 3
1 / -0

Gymnosperm species known from India is

A
119

B
209

C
64

D
48

Solution

Gymnosperms mean naked seeds; their ovules are naked and freely exposed to pollination, and the fertilized seeds are not enclosed by carpels. Great biodiversity exists on our planet. Millions of living plants and animal species are flourishing on Earth. An approximate of 1.7 million organisms are known to exist. 64 gymnosperm species are known from India.
So, the correct answer is '64'.
Question 4
1 / -0

Number of wildlife sanctuaries set up in India at present are

A
515

B
417

C
316

D
294

Solution

A naturally occurring sanctuary, such as an island, which protects species from getting hunted, predated or poached is called as a wildlife refuge. It is also known as a wildlife sanctuary. Being a protected area, it is a geographic territory within which wildlife is protected. 515 wildlife sanctuaries are present in India currently.
So, the correct answer is '515'.
Question 5
1 / -0

The factor that destroys plant biodiversity is

A
Biosphere reserves

B
Vulnerable ecosystems

C
Inaccessibility of habitats

D
Destruction of habitats

Solution

The factor that destroys plant biodiversity is destruction of habitats, wildlife species get extinct because of destruction of forest by deforestation.
So, the correct answer is 'Destruction of habitats'
Question 6
1 / -0

What is mainly responsible for extinction of wildlife?

A
Hunting for flesh

B
Destruction of habitats

C
Pollution of air and water

D
All the above

Solution

Hunting for flesh & skin, destruction of habitats by deforestation & polluted air & water leads to extinction of wildlife.
So, the correct answer is 'All the above'
Question 7
1 / -0

Convention on Biodiversity came into force on

A
29 Dec, 1993

B
6 June, 1992

C
3 October, 1994

D
4 October, 1993

Solution

The Earth Summit of Rio de Janeiro, also known as the United Nations Conference on Environment and Development (UNCED), was held in Rio de Janeiro from 3 to 14 June 1992. It resulted into the Convention on Biodiversity, a multilateral treaty, which entered into force on December 29, 1993. Three major goals were addressed in this convention which included: conservation of biodiversity; sustainable use of its components; and the fair and equitable sharing of benefits arising from the genetic resources.
So, the correct answer is '29 Dec, 1993'.
Question 8
1 / -0

Susceptibility to extinction is due to

A
Large body size

B
Small population

C
High trophic level

D
All of the above

Solution

When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out. The process is a completely natural part of evolution. But sometimes extinctions happen at a higher and a faster rate than usual. Factors such as large body size, small population and position at a higher trophic level favour extinction.
So, the correct answer is 'All of the above'.
Question 9
1 / -0

If at high altitudes, birds become rare, the plants likely to disappear are

A
Pine

B
Orchids

C
Oak

D
Rhododendrons

Solution

Pines seeds are mainly small and winged, and are anemophilous generally, which means that the seeds are dispersed by wind. However, some seeds are larger and they have only a vestigial wing and are needed to be dispersed by a bird. Thus, If at high altitudes, birds become rare, the plants likely to disappear are Pine plants. Oaks are not generally found at such high altitudes.
So, the correct answer is 'Pine'.
Question 10
1 / -0

Various forms of life should be conserved as they:

A
Will be lost otherwise

B
Have economic values

C
Contain diverse genetic resources

D
Are important for maintaining balance of nature

Solution

Biodiversity includes the enormous diversity of flora and fauna in the world. A great threat to it is now possessed by the increased rates of destructive activities. Various methods are being adopted by the authorities to conserve the species richness at various levels. If any species gets extinct, the gene pool of that species will be lost. So, the need for conservation of species is to conserve the different genetic resources.
So, the correct answer is 'Contain diverse genetic resources'.
