Importance of Species Diversity to the Ecosystem
BIOXII15: BIODIVERSITY AND CONSERVATION

344883 According to David Tilman

1 Increase in diversity contributes to higher productivity
2 Plots with more species showed less year to year variation in total biomass
3 Increase in diversity, leads to more competition
4 Both (1) and (2)

BIOXII15: BIODIVERSITY AND CONSERVATION

344885 According to the hypothesis proposed by environmental biologists, a relatively constant environment in tropics promotes

1 Niche specialization and lesser species diversity
2 Niche specialization and greater species diversity
3 Niche diversity and lesser species specialization
4 Niche diversity and greater species specialization
