All food chains begin with green plants because they are the only living things that can produce their own food. Green plants produce food by the process of photosynthesis.

The gradual but continuous change in a community is called ecological succession. If one community disappears, a different kind of community develops in place of the old one. 

Animals living in trees are called arboreal such as monkey.

Plants that grow on other plants using them only for support are called epiphytes. They have no roots in the soil. Epiphytes do not parasitize the plants they grow on.

Camouflage is the disguise used by animals to hide from their enemies. Men also use camouflage, particularly in wars. Most animals use camouflage to hide from predators or other animals that prey on them. Camouflaging is done by adopting matching colour to the surroundings, so that one looks like a part of it.

An animal which obtains food by hunting other animals is called a predator.
