Question
Which of the following is a correct statement regarding biodiversity?
- The tropical regions contain more biodiversity than temperate regions.
- The biosphere is made up of all those species, from the tiniest bacteria to the deadliest protists, the strangest fungi, the most beautiful plant, and the largest mammal.
- Colombia and Kenya, for example, each have over 1,000 breeding insect’s species.
- Although counting species is likely the most frequent way for comparing the biodiversity of different regions, biodiversity is weighted same for different species in practice.
Hint:
The regions that are present in the middle of the earth are rich in flora and fauna.
The correct answer is: The tropical regions contain more biodiversity than temperate regions.
The tropical regions face hot climate compared to the temperate zone. The hot weather of the tropical zone enables it to be having rich in species of flora and fauna. Many species still remain undisturbed and unknown. Classical examples of tropical zone is the western ghats which are rich in biodiversity.
The Western Ghats is one of the hottest biodiversity spots. It occurs along the western coast of India in Maharashtra, Karnataka, Tamil Nadu and Kerala. There is a high degree of species richness and endemism of flowering, non-flowering plants, reptiles, amphibians, insects, birds, fishes species. Many of the species are undiscovered and many of them threaten species occur in the Western Ghats. Thus, the correct option is B.
