Sometimes different feeding habits involve morphologically distinct phases, but they may involve only behavioral differences, and sometimes depend only on the immediate availability of different foods. Some life cycles involve a definite progression of particular hosts and depend on the life cycle of the host. Fungal feeders may have life cycles as short as 5 days.
