• C. ecological interaction
• D. endangered species

Answer 1

The correct option is B

biodiversity

A biodiversity hotspot is a biogeographic region with significant levels of biodiversity and these regions are in constant threats from humans. To qualify as a biodiversity hotspot, a region must meet two strict criteria:
(i) It must have a high percentage of plant life found nowhere else on the planet.
(ii) It must have 30% or less of its original natural vegetation. In other words, it must be threatened.
Around the world, 34 areas qualify as hotspots. They represent just 2.3% of Earth’s land surface, but they support more than half of the world’s plant species and nearly 43% of bird, mammal, reptile and amphibian species.
