BIOXII15: BIODIVERSITY AND CONSERVATION
344801
What is the approximate percentage of the earth covered by hotspots?
1 \(1.5 \%\) (less than \(2 \%\) )
2 \(2.5 \%\)
3 \(3.5 \%\)
4 \(4.5 \%\)
Explanation:
Although all the biodiversity hotspots put together cover less than 2 percent of the earth's land area.

Assertion : In-situ conservation is a type of biodiversity conservation Reason : It is the conservation of resources outside their natural habitat
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
Explanation:
In situ conservation is on site conservation or conservation of genetic resources in their natural habitats.

One of the following statements is incorrect with reference to biodiversity. Identify it.
1 Biodiversity increases from higher altitudes to lower altitudes.
2 Depletion in genetic diversity of crop plants is mainly due to the introduction of better varieties with high yield, disease resistance, etc.
3 The richest reservoirs of animal and plant life (species richness) with few or no threatened species are called "biodiversity hot spots".
4 Biodiversity decreases from the equator to polar regions.
Explanation:
A biodiversity hot spot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction.

What is common to the techniques (i) in vitro fertilisation, (ii) Cryopreservation and (iii) tissue culture?
1 All are in situ conservation methods.
2 All are ex situ conservation methods.
3 All require ultra modern equipment and large space.
4 All are methods of conservation of extinct organisms.
Explanation:
Option (1) can be easily ruled out. Tissue culture does not require large space and hence option (3) can be ruled out. Extinct organisms cannot be conserved, so option (4) can be rule out.
