Which region of India has the highest amphibian species diversity?

Eastern Ghats
Western Ghats
Thar Desert
Sundarbans
2

The Western Ghats have a greater diversity of amphibian species compared to the Eastern Ghats.

Which of the following is an incorrect statement about invasive species?

Invasive species can outcompete native species for resources.
Invasive species always increase local biodiversity.
Some invasive species alter ecosystem functions.
Invasive species can lead to the extinction of native species.
2

Invasive species often decrease biodiversity by displacing native species and disrupting ecosystem balance.

Which of the following is a correct statement about ecosystem services?

Ecosystem services include soil formation, climate regulation, and pollination.
Ecosystem services have no economic value.
Ecosystem services only benefit wildlife.
Ecosystem services are unaffected by human activities.
1

Ecosystem services are essential for human survival, including soil formation, climate regulation, and pollination.

Which of the following groups has the highest species diversity?

Fungi
Mammals
Birds
Reptiles
1

The Fungi group has more species than the combined total of fishes, amphibians, reptiles, and mammals.

Which of the following factors is NOT a direct cause of biodiversity loss?

Habitat destruction
Climate change
Over-exploitation
Speciation
4

Speciation increases biodiversity, while habitat destruction, climate change, and over-exploitation contribute to biodiversity loss.

Which of the following is an incorrect statement about species richness?

Species richness is highest in tropical rainforests.
Species richness is lower near the poles.
Species richness is uniform across all regions.
Higher species richness increases ecosystem stability.
3

Species richness varies across regions and is highest in tropical rainforests while decreasing towards polar regions.

Which biome has the highest annual net primary productivity?

Tundra
Deserts
Tropical rainforests
Grasslands
3

Tropical rainforests have the highest net primary productivity due to high temperatures, rainfall, and solar radiation.

Which of the following is an example of a species-rich ecosystem?

Temperate forests
Coral reefs
Grasslands
Deserts
2

Coral reefs are among the most species-rich ecosystems, supporting a high diversity of marine life.

Which of the following statements about ecosystem services is correct?

Pollination and nutrient cycling are examples of ecosystem services.
Ecosystem services only benefit wild species.
Ecosystem services are not essential for human survival.
Ecosystem services are not affected by human activities.
1

Ecosystem services such as pollination, nutrient cycling, and climate regulation are essential for both humans and wildlife.

Which of the following statements about species richness is true?

It remains constant across latitudes
It is higher in temperate regions
It is highest in tropical regions
It is independent of climate
3

Species richness is highest in the tropics due to stable climate and higher availability of resources.
