Topic 2 Biodiversity Classification of Living Organisms Gr 7 Natural Sciences - Term 1, Topic 2<br>
03
Classification systems Gr 7 Natural Sciences - Term 1, Topic 2 We classify objects when we group them with similar objects.
This makes it easier for us to make sense of the world around us.
We group things all the time:
for example, kitchen utensils are grouped
into cutlery, plates, bowls and pots.<br>

Classification of Living Organisms Gr 7 Natural Sciences - Term 1, Topic 2 Biologists sort living organisms into groups to make it easier to study them.
Grouping of living organisms is called biological classification.
Living organisms are divided into five main groups called KINGDOMS.
These are the bacteria, protists, fungi, plants and animals.<br>

Biodiversity on Earth Gr 7 Natural Sciences - Term 1, Topic 2 Each Kingdom is very large and it contains
