another. For example, grasshoppers jump and snakes slither
from one place to another.

Plants move through the growth process. Leaves and branches

move by growing towards light. Roots move downward and
sideways to absorb water.

Feeding

Living organisms need food. Animals eat plants and other
animals. For example, goats eat plants. Plants make their own

food.

Excretion

Living organisms remove waste products from their bodies.
The removal of waste products from the body is known as
excretion. Examples of waste products are urine, sweat and
carbon dioxide.

Waste products are harmful to the body. They must be removed
to enable living things to be healthy.
