According to David Tilman’s long term ecosystem experiments, the total biomass in plots with more species shows
1 High variation from year – to – year
2 Average variation from year – to – year
3 No variation from year – to – year
4 Less variation from year – to – year
Explanation:
Less variation from year to year

Communities with more species tend to be more stable than those less species. This was confirmed by
1 Alexander von Humboldt
2 Edward Wilson
3 Paul Ehrlich
4 David Tilman
Explanation:
David 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.
