QuestionEcology / biodiversity
Biodiversity in terms of species richness is maximum in:
- (a) natural grasslands.
- (b) semi-natural grasslands.
- (c) artificial grasslands.
- (d) well maintained and watered grasslands.
Answer: (a) natural grasslands.
Natural grasslands carry the highest species richness because they are old, undisturbed and have many niches. Semi-natural, artificial and managed (watered, fertilised) grasslands are dominated by a few species. Remember: management for yield lowers richness.
