D Correct answer
Explanation
Forests and biodiversity is key to all life forms. The richer the diversity of life, the greater the opportunity for medical discoveries, economic development and adaptive responses to such new challenges as climate change.
Forests are renewable resources which provide

If forest cover is reduced to half, what is most likely to happen on a long term basis? 

  1. Tribals living in these areas will starve to death.

  2. Domestic animals in these and joining areas will die due to lack of fodder.

  3. Large biomes will become deserts.

  4. Crop breeding programes will suffer due to a reduced ability of variety of germplasm.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

If forest cover is reduced to half, it would adversely affect the inhabitants. In rural areas, a community of people lives in the forest as a part of their tradition. They are completely dependent on the forest for their basic needs. They worship the trees and consider it as their ancestral belongings. The dependent tribals on a particular forest will be harmed by the clearing of the forest.

An ecologist wants to study the impact of habitat fragmentation on a forest ecosystem. Which of these would be the least impactful way to study the potential effect of habitat fragmentation while giving the most useful information? 

  1. Using a computer model to generate possible outcomes

  2. Observing a fragmented prairie ecosystem

  3. Deforesting an ecosystem and observing the effects

  4. Hypothesizing about what might be possible outcomes of fragmentation

  5. Experirmenting on a small patch of trees in a controlled area
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Effects of habitat fragmentation on forest ecosystem can be best studied in small and isolated populations. Prairie is a kind of dog. Prairie ecosystem is highly fragmented and effects of habitat fragmentation can't be studies easily in such fragmented ecosystems.
So, the correct answer is 'Observing a fragmented prairie ecosystem'.

Waking up to a bulbul's song in the morning is related to 

  1. narrow utilitarian

  2. broadly utilitarian

  3. ethical

  4. both (b) and (c).
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
The broadly utilitarian argument says that biodiversity plays a major role in many ecosystem services that nature provides. The fast dwindling Amazon forest is estimated to produce, through photosynthesis, 20 percent of the total oxygen in the earth’s atmosphere. Pollination (without which plants cannot give us fruits or seeds) is another service, ecosystems provide through pollinators layer – bees, bumblebees, birds and bats. There are other intangible benefits – that we derive from nature–the aesthetic pleasures of walking through thick woods, watching spring flowers in full bloom or waking up to a bulbul’s song in the morning.
So the correct option is 'broadly utilitarian'.

  1. 1960

  2. 1970

  3. 1964

  4. 1974
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

ICZN was adopted in 1964 with an object to assign a unique and scientific name of every taxon, it also regulates how these naming will be documented and used in literature. They provide universality in the naming or nomenclature.

So, the correct option is '1964'.

  1. providing nutritional support to plants

  2. to generate life continuity, flourishing distinctive structure to all species

  3. helping animals to survive in an environment

  4. All of above

In a national park, protection is provided to

  1. Entire ecosystem

  2. Flora and fauna

  3. Fauna only

  4. Flora only
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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 'Flora and fauna'.

Which of the following can be related to zoo and wildlife sanctuary?

  1. Zoo - animals are kept for public exhibition, Wildlife sanctuary - area within which animals are protected from possible dangers such as hunting.

  2. Zoo - area within which animals are protected from possible dangers such as hunting, Wildlife sanctuary - animals are kept for public exhibition.

  3. Zoo - artificial habitat, Wildlife sanctuary - conserves the natural habitat of animals.

  4. Both A and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Zoo is the ex-situ conservation strategy in which animals are conserved in an artificial habitat and are kept for public exhibition.
Wildlife sanctuary is an area within which animals are protected from possible dangers such as hunting in their natural habitat. Hence, it protects the animals as well as conserves the natural habitats of the animals.
Thus, the correct answer is option D.

Which of the following is not done in a wildlife sanctuary?

  1. Fauna is conserved

  2. Flora is conserved

  3. Soil and flora are utilized

  4. Hunting is prohibited
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • A wildlife sanctuary is a naturally occurring sanctuary, such as an island, that provides protection for wildlife species from hunting, predation, competition or poaching. 
  • A wildlife sanctuary is a place of refuge where abused, injured and abandoned captive wildlife may live in peace and dignity for the remainder of their lives. True wildlife sanctuaries do not breed or exploit for commercial activities. Fauna (animals) and flora (plants) are conserved.
  • So, the correct answer is 'Soil and flora are utilized'.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

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.

  1. Conservation of wildlife

  2. Studying wildlife biology

  3. Creating awareness about wildlife

  4. Preventing wild animals entering villages
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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. Whereas, a park in use for conservation purposes is known as a National park. These are methods of in-situ biodiversity conservation. In-situ conservation of biodiversity is done by conserving the species in their natural habitats. It is the best way of biodiversity conservation. 

So, the correct answer is 'Conservation of wildlife'.
