The species diversity of plants (22 per cent) is much less than that of animals (72 per cent). What could be the explanations to how animals achieved greater diversification?
Communities with more species diversity tend to be more stable than those with less species diversity. The high biodiversity makes the ecosystem more stable in productivity and more resistant towards disturbances such as alien species invasions and floods. Species richness and diversityis also essential for ecosystem's health as well as survival of human race on the earth.
