Question

The key criteria for determining a hot spot are:

• A. Biological
• B. Disruption of interaction networks
• C. Number of endemic species and degree of threat
• D. Habitat destruction

Answer 1

The correct option is C Number of endemic species and degree of threat

A biodiversity hotspot is a biogeographic region with significant levels of biodiversity and high degree of endemism which is threatened with destruction. Ecological hotspots are determined by four factors.
(i) Number of species diversity
(ii) Degree of endemism
(iii) The degree of threat to that habitat due to its degradation and fragmentation
(iv) Degree of exploitation

So, the correct option is 'number of endemic species and degree of threat'.
