intitially scientists only recognised two types of kingdoms, the animal kingdom and the plant kingdom ( kingdom plantae )
as scientists acknowledged that all organisms wouldnt fit into just these two catagories further groups were formed.finally there were five kingdoms formed.
- anamalia kingdom: multicellular eukaryotes that are heterotrophs. organsism that obtain energy as organic molecules by ingesting material from other organisms.
- plantae kingdom: multicellular eukaryotes that are autotrophs: meaning they can make their own molecules by photosynthesis.
- fungi kingdom: multicelluar eukaryotes who absorb nutrients from decaying material.
- protoctista kingdom: eukaryotes that photosythesise or feed or organic matter from other sources but are not included in the other kingdoms.
- ptokaryote system: prokaryote organisms including the bacteria and blue-green bacteria
