Detailed explanation-1: -David Tilmans long-term ecosystem experiments using outdoor plots 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 .
Detailed explanation-2: -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.
Detailed explanation-3: -Solution : David Tolman’s long-term ecosystem ecperiments using outdoor plots showed that increased diversity contributes to higher productivity.
Detailed explanation-4: ->The long-term ecosystem experiment by David Tilman reveals that plots of more species display fewer year-to-year variance in overall biomass. > In his experiment, he also found that greater diversity led to higher productivity.
Detailed explanation-5: -The hypothesis was formulated by American ecologist David Tilman. It predicts that if multiple species are competing for a single limiting resource, then whichever species can survive at the lowest equilibrium resource level (i.e., the R*) can outcompete all other species.
