Question 1
1 / -0

Which of the following is not a method of management of resources.

A
Meeting the needs of increasing population

B
Equitable distribution of natural resources

C
Present environmental damage

D
All

Solution

The recent concern about environmental and natural resources has arisen because these resources are not unlimited in nature. hence we manage these resources. The above options are ways of management of resources.
Question 2
1 / -0

Conservation of species in its natural habitat is

A
In-situ

B
Ex-situ

C
In-vitro

D
Both b and c

Solution

(In-situ =being in the original position; not having been moved Insitu conservation is onsite conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of tree species. It is the process of protecting an endangered plant or animal species in its natural habitat, either by protecting or cleaning up the habitat itself or by defending the species from predators. It is applied to conservation of agricultural biodiversity in agroecosystems by farmers, especially those using unconventional farming practices.
So, the correct answer is 'In-situ'
Question 3
1 / -0

An example of ex-situ conservation is

A
Seed bank

B
Sacred groves

C
National parks

D
Wildlife Sanctuary

Solution

Ex-situ conservation means literally, "off-site conservation". It is the process of protecting an endangered species of plant or animal outside of its natural habitat; for eg, by removing part of the population from a threatened habitat and placing it in a new location, which may be a wild area or within the care of humans. While ex situ conservation comprises some of the oldest and best-known conservation methods, it also involves newer, sometimes controversial laboratory methods. Seed band is also an example of ex-situ conservation.
So, the correct answer is 'Seed bank'
Question 4
1 / -0

Which of the following is not a measure to conserve environment ?

A
Conservation of soil from erosion

B
Crop rotation

C
Use of compost

D
None of these

Solution

Rotation of crop or mixed cropping protects the fertility of soil and provide which yield. Use of compost (organic matter) to enrich the soil.
Question 5
1 / -0

Why should we conserve biodiversity?

A
We should preserve the biodiversity we have inherited

B
A loss of diversity may lead to a loss of ecological stability

C
Both A and B

D
None of these

Solution

Biodiversity is the variety of different types of life found on the Earth and the variations within species. It is a measure of the variety of organisms present in different ecosystems. we must preserve it as we have inherited it and maintain the ecological stability.
Question 6
1 / -0

Wild buffalo is an endangered species because

A
Its population diminishing

B
It has become extinct

C
It is found exclusively in a particular area

D
Its poaching is strictly prohibited

Solution

An endangered species is a native species that faces a significant risk of extinction in the near future throughout all or a significant portion of its range.
Question 7
1 / -0

Which among the following help in replacing the use of conventional energy?

A
Solar energy

B
Coal

C
$$\displaystyle { KH }_{ 2 }{ PO }_{ 4 }$$

D
Petrol

Solution

As the population is growing at the fast pace, it is very important to manage the use to conventional resources. Replacing or reducing the conventional natural resource by non-conventional resources shall help in benefiting the future generation.
Question 8
1 / -0

The presence of diversity at the junction of territories of two different habitats is known as

A
Bottle neck effect

B
Edge effect

C
Junction effect

D
Pasteur effect

Solution

The increase in biodiversity at the junction of two different habitats is known as edge effect. This is termed as ecotone, not as Pasteur effect.
Question 9
1 / -0

Biogas is a result of ______

A
Anaerobic process

B
Aerobic process

C
Chemical agents

D
Mechanical process

Solution

Biogas constitutes 50-80% methane and rest carbon dioxide. Methane is produced by anaerobic degradation of organic matter.
Question 10
1 / -0

Which one of these is not concerned with wildlife conservation?

A
IVF

B
IUCN

C
WWF

D
IBWL

Solution

IVF (In Vitro Fertilization) is the process of fertilization of an egg and sperm in a laboratory condition, and then transferring the embryo to the uterus.
The international union for conservation of nature and natural resources (IUCN) is an international organization working in the conservation and sustainable use of natural resources.
The world wide fund (WWF) for nature is an international non-governmental organization founded on April 29, 1961, working in the field of the biodiversity conservation, and the reduction of humanity's footprint on the environment.
In 1952, Central Government of India constituted the Indian board for wild life (IBWL) for conserving the wildlife. Therefore IVF is not considered with wildlife conservation. Hence, the correct answer is option A.
