My hometown is under the foot of Mount Tai,Mount Tai is an eternal famous mountain,the animals and plants kind is abundant,there are huge ecosystems and a lot of interesting biological chains.
For example,green plants grass,the liver moss,etc.is eaten by the little insect,the little insect is eaten by the sparrow,and the sparrow is eaten by the snake,the final snake is prayed on by the eagle.This is an intact food chain.Corpse of hawk wait for microorganism resolve inorganic matter into bacterium fungi finally.In the ability transmission of this biological chain,energy decreases progressively step by step,fewer and fewer.
These biological chain for keep ecosystem equilibrate have important function,and have natural regulating action as to the environmental protection of the nature.
Today when the environmental problem is severe,it is our duty-bound responsibility to protect the living beings,it is forbidden to catch and wound and hurt the animals and plants,try one's bit for the green home.
