Options

  1. APlots with more species showed less year to year variation in total biomas
  2. BIncreased diversity contributed to higher productivity.
  3. CBoth the above
  4. DNone of these

Correct answer

C. Both the above

Step-by-step solution

We don’t know how these attributes are linked to species richness in a community, but David Tilman’s long-term ecosystem experiments using outdoor plots provide some tentative answers. Tilman found that plots with more species showed less year-to-year variation in total biomass. He also showed that in his experiments, increased diversity contributed to higher productivity.
