Pollution, climate changes, over-exploitation by humans etc. are responsible for changes in the ecosystem. Change in an ecosystem is responsible for depletion in biodiversity which directly or indirectly affects human beings and their surroundings. So it is important to conserve biodiversity. There are various methods like in-situ conservation, ex situ conservation by which we can conserve our biodiversity.
Q. How many biodiversity hot-spots are identified globally ?

Q. Protected areas are example of
Detailed Solution: Question 5
India is divided into 10 biogeographical regions. Varying physical conditions and species grouping India has rich species diversity. Tropics are a rich centre of biodiversity. Warm temperature, high humidity in tropical areas provide favourable conditions throughout the year. Rich diversity is important for stability, productivity for ecosystems.
Q. Which among the following represents diversity at ecosystem level ?
Detailed Solution: Question 6
India is divided into 10 biogeographical regions. Varying physical conditions and species grouping India has rich species diversity. Tropics are a rich centre of biodiversity. Warm temperature, high humidity in tropical areas provide favourable conditions throughout the year. Rich diversity is important for stability, productivity for ecosystems.
Q. When does the group represent minimum species diversity among vertebrates ?
Detailed Solution: Question 7
India is divided into 10 biogeographical regions. Varying physical conditions and species grouping India has rich species diversity. Tropics are a rich centre of biodiversity. Warm temperature, high humidity in tropical areas provide favourable conditions throughout the year. Rich diversity is important for stability, productivity for ecosystems.
Q. Which of the following taxon shows maximum species diversity ?
Detailed Solution: Question 8
India is divided into 10 biogeographical regions. Varying physical conditions and species grouping India has rich species diversity. Tropics are a rich centre of biodiversity. Warm temperature, high humidity in tropical areas provide favourable conditions throughout the year. Rich diversity is important for stability, productivity for ecosystems.
Directions : In the following questions a statement of Assertion (A) is followed by a statement of reason (R). Mark the correct choice as :
Assertion (A) : Tropics have more biodiversity.
Reason (R) : Climate of the tropical region is more seasonal.
Detailed Solution: Question 9

Warm temperature, high humidity in tropical areas provide favourable conditions throughout the year. Rich diversity is important for stability, productivity for ecosystems.
Q. What is the approximate ratio of animals and plant species in our country ?
Detailed Solution: Question 10
Read the following text and answer the following question on the basis of the same:
Excessive exploitation of species, whether a plant or animal reduces the size of its population, so it becomes vulnerable to extinction. Such as Dodo and passenger pigeons have become extinct due to over exploitation by humans. Thus, the world is facing accelerated rates of species extinctions, largely due to human interference.
Q. Identify a cause of biodiversity loss that is not included in the evil quartet?
Detailed Solution: Question 11
Read the following text and answer the following question on the basis of the same:
Excessive exploitation of species, whether a plant or animal reduces the size of its population, so it becomes vulnerable to extinction. Such as Dodo and passenger pigeons have become extinct due to over exploitation by humans. Thus, the world is facing accelerated rates of species extinctions, largely due to human interference.
Assertion : Pollution reduces species biodiversity.
Reason : Spillover of oil in the sea causes the death of several marine animals.
