Ecological hot spots present in India are

  1. One

  2. Two

  3. Three

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

Ecological hot spots are large areas of Earth's land surface which have high concentrations of plant endemism and also experience high rates of habitat loss. In India, 4 ecological hot spots are presently identified. The Himalayas, the Western Ghats, the Indo-Burma region and the Sundaland constitute the 4 biodiversity hot spots in our country. One of the major features of these places is the presence of numerous endemic species.

So, the correct answer is 'Three'.

According to, May's global estimates how many species of plants and animals, respectively, are yet to be discovered and described from India? 

  1. 50,000 and 90,000

  2. 3,00,000 and 90,000

  3. 3,00,000 and 1,00,000

  4. 1,00,000 and 3,00,000
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

If we accept May's global estimates only 22% of the total species have been recorded so far. If May's proposal for discovery of new species is accepted then there are probably more than 1,00,000 plant species and more than 3,00,000 animal species yet to discovered and described.

  1. Species diversity

  2. Genetic diversity

  3. Ecological diversity

  4. None of these.

A Correct answer
Explanation

Species diversity is the variety in the number and richness of the species of a region, Western Ghats have greater amphibian species diversity as compared to eastern ghats.

Vertical distribution of different species occupying different levels in dense vegetation is called.

  1. Stratification

  2. Species composition

  3. Standing crop

  4. Trophic structure

A Correct answer
Explanation

Vertical distribution of different species occupying different levels is called stratification. For example, trees occupy top vertical strata or layer of a forest, strubs the second and herbs and grasses occupy the bottom layers.

  2. population explosion

  3. air pollution

  4. biodiversity losses.

D Correct answer
Explanation

There are four major causes of biodiversity losses which are collectively called as the evil quartet. These are habitat loss and fragmentation, over exploitation, alien species invasion and co-extinctions.

Fill in the blanks with the most appropriate option. 
The values of z lies in the range of _______ regardless of the taxonomic group or the region.

  1. 0.1 to 0.2

  2. 0.3 to 0.8

  3. 0.1 to 1.0

  4. 0.6 to 1.8
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Alexander Von Humboldt observed that within a region richness increased with increased explored area, but only upto a limit. If a graph is plotted between species richness and area then we get a rectangular hyperbola. ON a log scale, the relationship becomes linear (straight line) and is described by the equation,

log S = log C + Z log A
where, S = species richness, Z = slope of the line (regression coefficient)
A = are and C = y-intercept
The value of Z ranges between 0.1 and 0.2 irrespective of the taxonomic group for a small area. But, if a larger area is taken into account then the slope is steeper and the vale of Z ranges between 0.6 and  1.2.
So the correct option is '0.1 to 0.2'.

Which of the following countries has the highest biodiversity?

  1. Brazil

  2. South Africa

  3. Russia

  4. India
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Brazil is the country with the highest biodiversity in the world. One-tenth of the world's overall species lives here.

India is on the eighth spot whereas South Africa is the thirteenth in the list.
Russia has comparatively low biodiversity due to its climate and availability of resources.
So the correct answer is ' Brazil'.

  1. At high latitudes

  2. At middle latitudes

  3. Near the equator

  4. In the desert southwest
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The 'land of the midnight sun' refers to regions near the poles where the sun remains visible at midnight during the summer. In the Northern Hemisphere winter, this phenomenon occurs at high latitudes in the Southern Hemisphere.
