This experiment through the simulation of the emblem of the ecological system of the pond, ina transparent jar with small stone, sediment, fish, water flea, algae, bacteria and the river, and made into a miniature of the closed ecosystem. Will the ecological bottle placed ina strong scattering light place, ecological bottles of three times daily observation, the record which animals and plants of the survival and survival time length, and ecology in the bottle of water quality, water flea, of the change of the algae, and further understand influence ecological the stability of the system of various factors.
