Correct option is D
Explanation-
To determine which habitat is most diverse, we must consider species diversity, which takes into account:
1. Species richness – the number of different species.
2. Evenness – how evenly the individuals are distributed among the species.
Habitat P
Species: 5 (richness = 5)
Abundance: Dominated by species 1 (120 out of 147 total)
Very uneven distribution → Low evenness
Low diversity overall
Habitat Q
Species: 8 (richness = 8)
All species have abundance ~15–20
Very even distribution
High diversity
Habitat R
Species: 8 (richness = 8)
But one species (1) dominates with 80
Others have much smaller values
Moderate diversity (higher than P, less than Q)
Decreasing order of diversity: Q > R > P
Correct Answer: Option d (Q, R, P)
