  • All of these

Ecological Diversity

  • It is more in India compared to Scandinavian countries like Norway

  • It is less in India comparative to Scandinavian countries like Norway

  • It is more in Australia comparative to India

  • Both (1) and (3)

It has taken millions of years of …….to accumulate this rich diversity in nature but we could lose all that wealth in …….if the present rates of species losses continue.

  • Evolution, less than 100 years

  • Evolution, less than two centuries

  • Founders effect, less than two centuries

  • Founders effect, less than one century

The total number of plant and animal species described so far is slightly  more than 1.5 million. This is reported by

  • IUCN- 2004

  • IUN-2006

  • IUCN-2006

  • IUN-2004

For many taxonomic groups, species inventories are more complete in

  • Temperate countries

  • Tropical countries

  • Grasslands

  • Both (2) and (3)

According to extreme estimates, which say that there is 20 to 50 million global species diversity is based on

  • Species richness of insects

  • Species richness of Arthropods

  • Species evenness of insects

  • Species evenness of Arthropods

According to Robert May, the global species diversity is

  • About 20 billion

  • About 7 billion

  • About 7 million

  • About 20 million

Which of the following statement is wrong about species diversity?

  • More than 70 per cent of all the species recorded are animals

  • Algae and fungi comprise no more than 22 per cent of the total

  • Here in this estimate, plants include algae, fungi, bryophyte, gymnosperms and angiosperms

  • 70 per cent of the total animals come from insecta

Among animals, which of the following is the most species-rich taxonomic group?

  • Insects

  • Molluscs

  • Crustacean

  • Other animal groups

Which of the following statement is true about biodiversity of Earth?

  • The number of fungi species in this world is more than the combined total of the species of fishes, amphibians, reptiles and mammals

  • The number of fungi species is less than combined total of the species of fishes

  • The number of fungi species is less than combined total of the species of amphibians and reptiles

  • The number of fungi species is less than combined total of the species of mammals and birds

Which of the following organisms are not estimated in terms of diversity?

  • Prokaryotes

  • Plants

  • Fungi

  • Mosses

Prokaryotes have not been estimated in terms of biodiversity. Which of the following reasons does not hold true?

  • Conventional taxonomic methods are not suitable for identifying microbial species

  • Many species are simply not culturable under laboratory conditions

  • Lichenes do not allow them to be assessed because of close association

  • Both (1) and (3)

India has only…….per cent of the world's land area, it's share of the global species diversity is an impressive ……. per cent

  • 2.4, 12

  • 2.4, 8.1

  • 8.1, 12

  • 8.1, 2.4

India is among 12 mega diverse countries of the world because

  • It bears 2.4 per cent area of the world's land and has a share of 12 per cent of global species diversity

  • It bears 2.4 per cent area of the world's land has a share of 8.1 per cent of the global species diversity

  • It has several groups to protect environment which are not in other countries

  • Government of India is aware of the loss of Biodiversity but other governments are not

India holds which of the following Biodiversity data true?

  • 45000 species of plants

  • 50000 species of animals

  • 90000 species of plants

  • 45000 species of animals

According to May's estimate, how many species are yet to be discovered?

  • 22 per cent

  • 78 per cent

  • 30 per cent

  • 50 per cent

According to May's estimate, how many animal species are yet to be discovered in India?

  • Around 50000

  • More than 300000

  • More than 100000

  • Around 45000

Which of the following is not a pattern of Biodiversity?

  • Latitudinal Gradients

  • Species area relationship

  • Fragmentation

  • Both (2) and (3)

Latitudinal gradient in diversity says that

  • Species diversity decreases as we move away from the equator towards the poles

  • Species diversity increases as we move away from the equator towards the poles

  • There are few exceptions to this pattern of Biodiversity

  • Both (1) and (3)

Which of the following will harbor more species than temperate regions?

  • Tropics: latitudinal range 23.5 degree North to 23.5 degree South

India has more than 1200 species of birds. This is because

  • India with much of it's land area in the tropical latitudes

  • India with much of it's land area in temperate latitudes

  • India with it's considerable land area in polar latitudes

  • India with much of it's land area in different altitudes
