<p>A natural ecosystem reproducing method comprising a step of preparing as a container, for example, a box-like bed (12) with its top open for receiving living things such as plants, for example, green vegetables, rootcrops and fruit vegetables and aquatics like fishes, shells and crustaceans and growing such plants and aquatics, a step of storing in the bed a culture solution containing nutrients for growth of such plants and aquatics, a step of waving the culture solution by means of a wave maker (44,46) which moves vertically a rectangular parallelepiped wave-making element (52,58) disposed above the bed and made of, for example, a synthetic resin and a step of periodically and vertically changing the level of the culture solution stored in the bed to thereby cause a ebb and flow phenomenon in the bed. <IMAGE></p> |
