In hotspots endemic species are observing and less inter-specific competition is observed species richness is observed but accelerated species loss is not observed because hotspots is declared for species conservation.

Introduction:
Biodiversity hotspots are regions with a high level of biodiversity that are under threat from human activities. These areas are recognized for their significant conservation value and support a wide range of endemic species. However, not all characteristics are observed in biodiversity hotspots. In this case, option (B) lesser inter-specific competition is not observed in biodiversity hotspots.

Explanation:
1. Endemism:
Endemism refers to the occurrence of species exclusively in a particular area or region and not found anywhere else. Biodiversity hotspots are known for their high levels of endemism. These regions often have unique ecosystems and habitats that support the survival of species found nowhere else on Earth.

2. Lesser inter-specific competition:
Inter-specific competition occurs when different species compete for limited resources such as food, water, or territory. In biodiversity hotspots, there can be intense competition among species due to the high diversity and limited resources. Therefore, option (B) lesser inter-specific competition is not observed in biodiversity hotspots.

3. Accelerated species loss:
Biodiversity hotspots are highly threatened areas where species loss is occurring at an accelerated rate. Human activities such as deforestation, habitat destruction, pollution, and climate change are major factors contributing to the loss of species. The high level of endemism and unique species composition in these hotspots makes them particularly vulnerable to extinction.

4. Species richness:
Species richness refers to the number of different species present in a given area. Biodiversity hotspots are known for their high species richness. These regions often have diverse ecosystems that support a wide variety of species. The presence of numerous species contributes to the overall biodiversity and ecological value of these areas.

Conclusion:
In summary, option (B) lesser inter-specific competition is not observed in biodiversity hotspots. These hotspots are characterized by high levels of endemism, accelerated species loss, and species richness. The competition among different species for limited resources is a common feature in these regions, which further emphasizes the need for conservation efforts to protect their unique and fragile ecosystems.
