Questions Related to basis of classification in animals

Which of the following is wrongly matched?

  1. Temperate zone - $20^{\circ}\, -\, 40^{\circ}$ latitude

  2. Hypolimnion -Thermal stratifications in lakes

  3. Ozone layer - Stratosphere

  4. Profundal zone - Dark zone


Correct Option: A
Explanation:

The north temperate climate extends from the 'Tropic of Cancer' (approximately 23.5 north latitude) to the arctic circle (approximately 66.5 north latitude). The south temperate zone extends from the tropic of capricorn (approximately 23.5 south latitude) to the antarctic circle (at approximately 66.5 south latitude). 

Latitude range with maximum species diversity is 

  1. $23.5^0 N -66.5 ^0 N $

  2. $23.5^0 S -66.5 ^0 S $

  3. $23.5^0 N -23.5 ^0 S $

  4. $66.5^0 N -66.5 ^0 S $


Correct Option: C
Explanation:
  • Latitudinal gradients of biodiversity are biogeographic patterns that quantify the ways in which taxonomic, phylogenetic, functional, genetic, or phenetic biodiversity change with the latitudinal position on the surface of the earth.
  • Species richness, or biodiversity, increases from the poles to the tropics. So the latitude range with maximum species diversity is the equator region, which is option C.

Rate of photosynthesis is maximum at

  1. Equator

  2. Tropic of Cancer

  3. Tropic of Capricorn

  4. Arctic circle


Correct Option: A
Explanation:

The rate of photosynthesis would be maximum at the equator because the the rate of photosynthesis depends on the light intensity. Maximum intensity of light occurs at the equator, and gradually decreases with increasing distance from the equator to the south and north poles. So the correct answer is 'Equator'.

Biological diversity day is

  1. 5 June

  2. 21 March

  3. 3 October

  4. 22 May


Correct Option: D
Explanation:

Biodiversity day or the Biological diversity day is a UN sanctioned day celebrated internationally. It addresses the promotion of biodiversity issues. Currently, the day is held on May 22. Earlier, it was held on December 29 to celebrate the day in which the Convention on Biological Diversity came into action.

So, the correct answer is '22 May'.
