    Hii, can sombody help me on just a couple of questions...

    1) Simposon's index of diversity for
    heavily grazed grassland: 0.87
    lightly grazed grassland: 0.54
    suggest why the value for heavily grazed grassland is higher than that for lightly grazed grassland???

    2) Mean plant height is greater in lightly grazed grassland than in heavily grazed grassland. Explain how this could influence the transpiration rate of smaller and shorter plants growing in lightly grazed grassland???

    Thnx
