"We can't imagine the world without insects and birds". Suggest two methods to conserve them.

View Answer

Methods of conservation for Birds:
  • Captive breeding, or ex-situ conservation, has been used in a number of instances to save species from extinction. The principle is to create a viable population of a species in either zoos or breeding facilities, for later reintroduction back into the wild.
  • As the loss and destruction of habitat is the most serious threat facing many bird species, conservation organizations, and government agencies tasked with protecting birds work to protect areas of natural habitat. This can be achieved through purchasing land of conservation importance, setting aside land or gazetting it as a national park or other protected areas, and passing legislation preventing landowners from undertaking damaging land use practices or paying them not to undertake those activities.

Methods of conservation for Insects:
  • The key to insect conservation is to protect and - where necessary - to enhance or create habitats throughout the landscape so that even the least mobile species can find somewhere to live when conditions become locally unsuitable.
  • Harm from pesticides can be reduced by using methods such as integrated control, in which different methods are combined so as to minimize or eliminate the dosage. If pesticides have to be applied, they should be kept away from hedgerows, watercourses and other non-target habitats.

American water plant that has become a troublesome water weed in India is

A

Cyperus rotundus

B

Eichhornia crassipes

C

Typha latifolia

D

Trapa bispinosa

View Answer

Eichhornia crassipes, commonly known as water hyacinth, is an aquatic plant native to the Amazon basin. It is often considered a highly problematic invasive species outside its native range. When not controlled, water hyacinth will cover lakes and ponds entirely; this dramatically impacts water flow, blocks sunlight from reaching native aquatic plants, and starves the water of oxygen, often killing fish and other aquatic animals. Hence option B is correct.

World wild life week is

A

First week of September

B

First week of October

C

Third week of October

D

Last week of October

View Answer

World wild life week is celebrated on October - 2nd to 8th. It is celebrated to  protect the fauna. It was started in 1952 with some major steps in order to protect the Indian wild life  and enrich the diversity in the fauna. Indian Board of Wild Life was a regulatory body set up by the Indian government to spread awareness for wild life preservation.

View Answer

The population of an Endangered animal is very small. If the population reduces to zero, the animal will become Extinct.

Wildlife conservation means the protection and preservation of

A

Ferocious wild animals only

B

Wild plants only

C

Non-cultivated plants and non-domesticated animals

D

All the above living in natural habitat

View Answer

Wildlife conservation is the strategy to protect wild plant and animal species and their habitats. The goal of wildlife conservation is to ensure that nature will be maintained for next generations and also to recognise the importance of wildlife
So, the correct answer is 'All the above living in natural habitat'

Conservation is

A

Protection of natural resources

B

Management of natural resources

C

Proper use of natural resource

D

All of the above

View Answer

  • Conservation means preservation from loss, waste or degradation of a resource, so as to last indefinitely.
  • Management of a resource is controlling the use of the resource in such a way so as to provide sustained and equitable availability. The two are important because exhaustible resources are undergoing rapid depletion.
  • Lifetime of a resource is the period along the time scale up to which its availability for human use is assured on global basis. 
  • Depletion time is the period along with the timescale when the availability of resources will decrease to such an extent that it is unable to meet the human requirements.
    Hence, option D is correct.

New 'Wild Life Protection Act' was passed in

A

1962

B

1972

C

1982

D

1987

View Answer

'Wild Life Protection Act' was passed in 1972 and amended in 1991. According to this act, hunting of animals and exploitation of certain plants are completely prohibited. It allows for setting up and managing national parks, sanctuaries, zoos, controls trade in wildlife and wildlife products and trophies. 

Animals like tiger are dangerous for humans; even then Project Tiger has been launched. Why should we protect such animals?

View Answer

The tiger is a unique animal which plays a pivotal role in the health and diversity of an ecosystem. It is a top predator which is at the apex of the food chain and keeps the population of wild ungulates in check, thereby maintaining the balance between prey herbivores and the vegetation upon which they feed.
Project Tiger aims at ensuring a viable population of Bengal tigers in their natural habitats, protecting them from extinction, and preserving areas of biological importance as a natural heritage forever represented as close as possible the diversity of ecosystems across the tiger's distribution in the country. 

Which of the following is true about conservation and preservation?
I. Protects the ecosystem from destruction
II. Prevents the depletion of natural resources.
III. Maintains the population of endangered plants and animal species.

A

I only

B

I and II only

C

II and III only

D

I, II and III

View Answer

Conservation is the sustainable use and management of natural resources, both renewable and non-renewable. Preservation is the strict keeping aside of natural resources so as to prevent the use or contact of resources by humans or by human intervention. 
Conservation ensures that resources are not consumed faster than they can be replaced. It also ensures that  sufficient quantities are maintained for future generations to utilise. Thus, it is involved in preventing the depletion of natural resources. The main purpose of conservation and preservation is to protect the ecosystem from destruction due to increased use of or consumption of resources. Conservation is also carried out to protect plant and animal species from being extinct. It maintains the population of endangered species by protecting and restoring the habitats and maintaining the essential ecological processes and life-support systems. 
Thus, the correct answer is option D.
