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.

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. 2 to 4

  2. 4 to 5

  3. 3 to 5

  4. 9
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Acid rain in Europe and Scandinavia, caused by industrial emissions, typically results in precipitation with a pH range of 3 to 5.

During the winter in the Northern Hemisphere, the "land of the midnight sun" would be found:

  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.

The main reason(s) for warm summers in northern middle latitudes is that:

  1. The earth is closer to the sun in summer

  2. The sun is higher in the sky and we receive more direct solar radiation

  3. The days are longer

  4. Only (b) and (c) are correct
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Warm summers in northern middle latitudes are primarily caused by the tilt of the Earth, which results in the sun being higher in the sky (more direct radiation) and longer daylight hours. The Earth's distance from the sun is not the primary cause of seasonal temperature changes.

What is altitude of menopause?

  1. 80 km

  2. 45 km

  3. 50 km

  4. 90 km
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The mesopause is located at approximately 80-85 km altitude. This is the boundary between the mesosphere and thermosphere and is the coldest part of the atmosphere. The question uses 'menopause' which appears to be a typo for 'mesopause' (a common atmospheric science term). 80 km is the closest approximation among the options.
