Weekly Quiz Competition

Question 1
1 / -0

Most of the endangered species are victims of

A
Acid rain

B
Competition with introduced species

C
Habitat destruction

D
Over-hunting

Solution

Endangered species are prone to become extinct. 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, massive habitat loss and position at a higher trophic level favor extinction. As forests are the main habitat for the wild animals, their loss favors the extinction of the same.
So, the correct answer is 'Habitat destruction'.
Question 2
1 / -0

Which of the following practices has caused maximum damage to the diversity of Indian forests?

A
Selective harvesting

B
Block cutting

C
Taungya cultivation

D
Jhum cultivation

Solution

Jhum cultivation, also known as the slash and burn agriculture, is the process of growing crops by first clearing the land of forests and burning them thereafter. It is also known as shifting agriculture. The burnt soil contains potash which helps in increasing the nutrient content of the soil. This process has led to the maximum damage to the Indian forests as they are cleared for this process.
So, the correct answer is 'Jhum cultivation'.
Question 3
1 / -0

The only floating national park in the world is

A
Keibul Lamjao National Park

B
Keoladeo Ghana National Park

C
Chilka Lake Sanctuary

D
Nat Sarovar Sanctuary

Solution

Brow Antlered Deer is found in Keibul Lamjao National Park, Manipur. It is the only floating national park in the world. 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. Flora and fauna are provided immense protection in such areas. Currently, in India, we have 166 national parks.
So, the correct answer is 'Keibul Lamjao National Park'.
Question 4
1 / -0

Which national park is the new home of Indian one-horned rhinoceros?

A
Kanha

B
Dudhwa

C
Corbett

D
Bandhavgarh

Solution

Dudhwa National Park is famous for conserving Indian one-horned rhinoceros. It is located in Uttar Pradesh. 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. Flora and fauna are provided immense protection in such areas. Currently, in India, we have 166 national parks.
So, the correct answer is 'Dudhwa'.
Question 5
1 / -0

Who gave rivet popper hypothesis?

A
E.P. Odum

B
Paul Ehrlich

C
Ram Deo Misra

D
A. Tansley

Solution

Paul Ehrlich, an ecologist, gave the rivet popper hypothesis. The hypothesis explains the important role played by each species in an ecosystem. It compares the ecosystem with an airplane and says if you keep popping rivets (species), the plane will no longer fly. It also explains the role of different species in an ecosystem.
So, the correct answer is option B.
Question 6
1 / -0

India now has

A
10 Biosphere Reserves, 50 National Parks and 400 Wildlife Sanctuaries

B
14 Biosphere Reserves, 50 National Parks and 400 Wildlife Sanctuaries

C
10 Biosphere Reserves, 90 National Parks and 448 Wildlife Sanctuaries

D
18 Biosphere Reserves, 106 National Parks and 515 Wildlife Sanctuaries

Solution

Biosphere reserves are sites to protect unusual plant and animal species.
A natural park is a protected natural area for resource management, with limited agricultural developments.
Wildlife Sanctuary is an area to protect wild animals and plants.
Currently, India has 18 biosphere reserves, 106 National Parks, and 515 Wildlife Sanctuaries.
Hence, the correct answer is option (D).
Question 7
1 / -0

The relation between species richness and area is correctly depicted by

A
log S = log C - Z log A

B
log S = Z log A

C
log S = log C + Z log A

D
log S = log C

E
log C = log S + Z log A

Solution

The relationship between the area of a habitat, or of part of a habitat, and the number of species found within that area is described by the species-area curve. It says that log S = log C + Z log A. Here S is the number of species, A is the habitat area, and Z is the slope of the species-area relationship. Larger areas tend to contain larger numbers of species.
So, the correct answer is 'log S = log C + Z log A'.
Question 8
1 / -0

Kanha National Park is located in and is famous for

A
Madhya Pradesh, Tiger

B
Madhya Pradesh, Elephant

C
Odisha, Elephant

D
Assam, Tiger

Solution

Kanha National Park is located in Madhya Pradesh and is famous for tigers. 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 'Madhya Pradesh, Tiger'.
Question 9
1 / -0

Which scientist proposed alpha types species diversity?

A
Bentham and Huxley

B
Linnaeus

C
Whittaker

D
Eichler

Solution

The local species pool is known as alpha diversity. It is also the diversity present within the community. The term was introduced by R. H. Whittaker. Example of such diversity includes high tree diversity throughout the Amazon Rainforests of Ecuador. Generally, gamma diversity = alpha diversity x beta diversity.
So, the correct answer is 'Whittaker'.
Question 10
1 / -0

Which of the following is referred as Evil Quartet with reference to loss of biodiversity?

A
Species richness, extinctions, deforestation, erosion

B
Habitat loss and fragmentation, overexploitation, alien species invasion, co-extinction

C
Overexploitation, grazing, decompositon, extinction

D
Habitat destruction, co-extinction, deforestation, species richness

E
Grazing, erosion, deforestation, species richness

Solution

Jarod Diamond in 1984 listed four principal mechanisms for the loss of biodiversity. It was known as the 'Evil quartet'. It was also known as four horsemen of the ecological apocalypse. The four mechanisms were:-
a) overhunting (or overexploitation),
b) introduced species,
c) habitat destruction and
d) chains of linked extinctions (trophic cascades, or co-extinctions).
So, the correct answer is 'Habitat loss and fragmentation, overexploitation, alien species invasion, co-extinction'.
