Question

Which one of the following is not observed in Biodiversity Hotspot?

• A. lesser interspecific competition
• B. accelerated species loss
• C. endemism
• D. species richness

Answer 1

The correct option is A

lesser interspecific competition

The correct option is A.

The explanation of the correct answer:

1. A biodiversity hotspot is a biogeographic region where a rich number of biodiversity is observed but at the same time, it is also threatened with destruction.
2. Biodiversity hotspots include a large number of diverse species leading to high species richness.
3. Interspecific competition means competition among different species for food, habit, habitat, etc.
4. In Biodiversity Hotspot, there is n number of species creating more interspecific competition.
5. Hence lesser interspecific competition cannot be observed in Biodiversity Hotspot.

The explanation of the incorrect answers:

Option B:

1. accelerated species loss is nothing but loss of species diversity in large numbers.
2. There are a large number of species and great interspecific competition which will lead to species loss due to less food, habitat, etc.
3. Due to many natural calamities also, species loss is accelerated in Biodiversity Hotspot.

Option C:

1. When a particular species is confined to a particular geographical area, and cannot be found in other places, then the species is said to be endemic and the phenomenon is Endemism.
2. Endemism is a characteristic feature of biodiversity hotspots.

Option D:

1. The number of different species acquiring a particular area indicates the species richness of that particular area.
2. Biodiversity hotspots have great species richness.

Final answer:

Lesser interspecific competition is not observed in Biodiversity Hotspot.
