Grazing

Grazing is feeding on growing herbage, attached algae, or phytoplankton. Grazing differs from predation because the organism being eaten is not killed, and it differs from the feeding of parasites by the fact that the two organisms do not stay together very long, nor is the grazer so limited in what it can eat. Grazing, in some contexts, is distinguished from browsing in that grazers eat grass and browsers eat leaves from trees.
