Primitive plants are responsible for converting the poisonous atmosphere of Earth into an oxygen rich atmosphere has supports animal life. Trees help to maintain low levels of carbon dioxide, thereby reducing the greenhouse effect which threatens to make the earth uncomfortably warm.
Soil benefits from trees as their far-reaching hold the soil in place, preventing erosion. Trees improve soil quality as their leaf litter makes perfect compost. Some trees, for example acacias have bacteria living in their roots. The bacteria convert nitrogen from the air into nitrates which the tree can use to grow and reproduce, whilst the soil is also enriched.
The leaves of trees are eaten by many insects as well as monkeys, elephants, giraffes, kudus and bush-bucks. Even fallen dead leaves are eaten - they are a favorite food of the blue duiker. Flowers are eaten by monkeys and nectar by birds, insects and bats. Many fruits are eaten by animals, some of which aid seed dispersal.
Trees provide nest sites for birds. The leafy branches make good hiding places and are difficult for most predators to reach - even non-breeding birds roost in trees at night. Woodpeckers, barbets and hornbills nest in holes in trees. Very large, old trees frequently develop a hollow centre, a favorite breeding and roosting place for bats. When dead, their rotting wood is a source of food for insects and their predators.

The inner bark of certain trees provides latex, main ingredient of rubber. Acacias produce sap used in gum manufacture, and the maples of North America yield edible maple syrup. Several palms produce a watery sap which is drunk as palm wine, or can be fermented and distilled into a powerful spirit.
Trees are great producers of edible fruits - apples„ bananas, plums, papayas, avocados, olives, nuts, oranges, litchis - the list of commercially grown fruits is almost endless. Many wild species are of economic importance, including the Brazil nut and Marcela. Wild fruits eaten by rural people include monkey oranges and wild plum.
