Which one of the following is not observed in biodiversity hotspots ?
- Lesser interspecific competition
- Species richness
- Endemism
- Accelerated species loss
The Correct Option is A
Solution and Explanation
The correct option is(A): Lesser interspecific competition.
Areas characterized by significant concentrations of species endemism and facing substantial habitat loss are termed ecological hotspots, commonly known as biodiversity hotspots. They constitute approximately 2.3% of the Earth's land surface and currently, there are 36 such hotspots worldwide. Meeting stringent criteria, an area becomes an ecological hotspot by harboring a minimum of 1,500 species of vascular plants that are exclusively found there (referred to as "endemic" species) and having experienced the loss of at least 70% of its original native vegetation. Due to the abundance of species in these regions, there is a noteworthy level of competition between different species for resources.
Therefore, the correct option is Lesser interspecific competition.
Top Questions on Biodiversity and Conservation
- In nature, populations of different species in a habitat do not live in isolation but interact in many ways. Depending on the outcome, these interactions between two species are classified as competition, predation, parasitism, commensalism, amensalism, and mutualism. Through these interactions, trophic energy transfer is facil itated. Some predators help in controlling their prey populations, whereas plants have evolved diverse morphological and chemical defenses against herbivores.

Biodiversity and Conservation
The term ‘biodiversity’ is derived from the two words- ‘bios' which means life and ‘diversity’ i.e, differentiation or variation. Edward Wilson, the sociobiologist was the first to popularise the term ‘biodiversity’ in the year 1992. The term implies the occurrence of various plants and animals along with their variants such as biotypes, ecotypes and genes on earth. In our biosphere, the immense diversity or heterogeneity remains not only at the species level but also, at every level of biological organization that ranges from macromolecules in the cells to biomes.
Biodiversity and Conservation is a topic covered under the fifteenth chapter and Unit 5 of NCERT class 12 biology.
