Question

David Tilman’s long-term ecosystem experiments using outdoor plots showed that

• A. increased diversity contributed to lower productivity
• B. increased diversity have no impact on productivity
• C. increased diversity contributed to higher productivity
• D. increased diversity have unpredictable impact on productivity

Answer 1

The correct option is C increased diversity contributed to higher productivity

David Tilman did some experiments using outdoor plots to explain species-biomass relationship.

He showed that plots with more number of species, i.e, higher biodiversity exhibited higher productivity and less year to year variations in biomass.

Hence the correct option is
b. increased diversity contributed to higher productivity
