• Why is the pyramid inverted?

4
Species

• The smallest group of organisms classified which
  can interbreed with each other to produce fertile
  offspring
• Scientific name unique to all organisms
• e.g. scientific name of
• human Homo sapien
• Sugar maple _______________ (?)
• Red maple _______________ (?)
• Striped maple _______________ (?)

5
Six Kingdom System

• Protists
• Fungi
• Animals
• Plants
• Archaebacteria
• Eubacteria

6
All are made of cells

• Membrane
• Organelles tiny organs
• DNA ( in or not in a nucleus)

7
A cell with a nucleus
8
A cell without a nucleus
9
All contain DNA
10
Multicellular tissue
11
Protists

• Unicellular microscopic
• Nucleus present
• Nucleus the Brain of the cell controls cells
  actions
• Autotrophic (self-feeder, makes food by
  photosynthesis) or
• Heterotrophic (other-feeder)

12
Fungi

• Have nuclei
• Made up of hyphae
• Stringy threads of cells
• No root, stem and leaf
• Saprophytic or parasitic
• Saprophytic feed on dead substances
• Parasitic obtain nutrients from living organisms
  

13
Animals

• Have nuclei
• Multi-cellular
• Divided into two groups according to the presence
  or absence of backbone
• Invertebrates without backbone
• Vertebrates with backbone
• (Phylum Chordata)

15
Plants

• Have nuclei
• Multicellular
• perform photosynthesis
• Autotrophic make own food
• Can be divided into two groups
• Non-flowering plants
• Flowering plants

16
Eubacteria

• Unicellular, microscopic
• No nucleus
• Saprophytic or parasitic
• Saprophytic feed on dead substances
• Parasitic obtain nutrients from living organisms

17
Archaebacteria

• Ancient bacteria
• Unicellular, microscopic
• No nucleus
• Heterotrophic (other feeder, or
• Autotrophic (self-feeder)
