In addition to large mammals, many arboreal mammals consume the leaves, fruit and flowers of trees. While few birds consume leaves, a great many birds eat the fruit and seeds that come from trees, including blue jays, sparrows and cardinals.

Insects such as locusts, grasshoppers or leaf hoppers can quickly strip a tree of all of its leaves. Additionally, many caterpillars subsist on the leaves of fruit trees.
Termites eat xylem, but they typically do not eat living tissue. Because they are one of the few animals capable of extracting the energy found within xylem tissue, termites are a very important component of all ecosystems. Without termites, ecosystems would fill up with too many dead trees.Learn more about Botany
