What did David Tilman's experiments conclude about the relationship between species richness and ecosystem health?
  1. Plots with more species showed less year:to:year variation in total biomass
  2. Increased diversity decreased productivity
  3. There is no relationship between species richness and ecosystem health
  4. The relationship between species richness and ecosystem health is not understood

Solution

Tilman's experiments showed that plots with more species showed less year:to:year variation in total biomass and that increased diversity contributed to higher productivity.
