Write whether the following statements are true or false . (i) Communties with more species tend to be more stable that those with less species. (ii) David Tilman found that plots with less species showed less year-to-year variation in total biomass. (iii) A stable community must be resistant to invasions by ecotic species. (iv) Effect of reduction in diversity has been explained by Alexander von Humboldt through rivet popper hypothesis.
