Question

According to David Tilman's long-term outdoor plot experiments, what significant observation was made about species-rich communities regarding total biomass variation?

Options

• Species-rich communities show minimal variation in total biomass

• Species-rich communities show maximum variation in total biomass

• Species-rich communities show unpredictable biomass patterns

• Species-rich communities show cyclic biomass fluctuations

Answer 1

Tilman's Finding demonstrated through long-term outdoor plot experiments that species-rich communities show minimal variation in total biomass across different time periods. This empirical evidence proves that greater species diversity leads to more stable and consistent biomass production, supporting the theoretical foundation for ecosystem stability.
