These innumerable organisms are immersed in water or in dead animals and plants, and in all manner of moist organic products. By breaking down organic combinations, they produce decay. Largely through their agency, and that of many true but microscopic fungi, all things pass into soil and gas. Thus are the bodies of plants and animals removed and the continuing round of life is maintained. Some parasites are green- leaved. Such is the mistle- toe (Fig. 136). They anchor themselves on the host and absorb its juices, but they Fig. 136.â American Mistletoe ' â ' GROWING ON A WALNUT BRANCH. also appropriate and use.
