There
are millions of different living things. All living things are
divided up into five main groups:
Plants
Animals Fungi Bacteria Protoctista
These
five groups are called kingdoms. The plant
kingdom and animal kingdom are the
two largest. Plants are organisms which can make their own food
using energy from the sun and animals cannot. For this unit
you need to know how the animal kingdom is divided up into groups.
Animals can be divided into two main groups: invertebrates
(animals without backbones)and invertebrates
(animals with backbones). The main groups in the animal
kingdom are shown in the diagram below:
Try
