1. Natural Sciences Grade 7 Term 1: Life and Living Biodiversity (PPT 1)

2. Topic 2 Biodiversity Classification of Living Organisms Gr 7 Natural Sciences - Term 1, Topic 2

3. Classification systems 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. Gr 7 Natural Sciences - Term 1, Topic 2

4. Classification of Living Organisms 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. Gr 7 Natural Sciences - Term 1, Topic 2

5. Biodiversity on Earth Each Kingdom is very large and it contains many different types of organisms. 4000 Bacteria 66000 Fungi 150000 Protists 290000 Plants 1200000 Animals Gr 7 Natural Sciences - Term 1, Topic 2

6. Meet Carl Linnaeus Gr 7 Natural Sciences - Term 1, Topic 2

7. Who was he? Famous for his work in Taxonomy: the science of identifying, naming and classifying organisms (plants, animals, bacteria, fungi, etc.). He was born in 1707 in R shult, Sweden. He was the eldest of five children. His father, Nils, was a minister and a keen gardener. Gr 7 Natural Sciences - Term 1, Topic 2
