3. Classification of living things Organisms can be classified into one of three domains of life: Organisms can be classified into one of three domains of life: –Archaea –Bacteria –Eukarya Figure 12-1

4. Classification of marine organisms Marine organisms can be generally classified into one of three groups based on habitat and mobility: Marine organisms can be generally classified into one of three groups based on habitat and mobility: 1.Plankton (floaters) Phytoplankton (drifting plants and algae) Phytoplankton (drifting plants and algae) Zooplankton (drifting animals) Zooplankton (drifting animals) 2.Nekton (swimmers) 3.Benthos (bottom dwellers)
