  1. Stratification

  2. Species composition

  3. Standing crop

  4. Trophic structure

Show answer
Correct Option: A
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.

  1. forest loss

  2. population explosion

  3. air pollution

  4. biodiversity losses.

Show answer
Correct Option: D
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.

  1. 0.1 to 0.2

  2. 0.3 to 0.8

  3. 0.1 to 1.0

  4. 0.6 to 1.8

Show answer
Correct Option: A
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

Show answer
Correct Option: A
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'.
