WebThe gills are a fish's gas exchange system. The fish opens its mouth to let water in, then closes its mouth and forces the water through the gills and out through the operculum (gill cover). This means the water flows … WebGas exchange allows the organisms to replenish the oxygen and eliminate the carbon dioxide. In the case of plants during photosynthesis, it allows release of oxygen and replenishment of carbon dioxide (plants also need oxygen, just like animals, for respiration). Oxygen is used to release energy as ATP during respiration. circulatory powerpoint
