6. Kingdom - Archaea Methanogens Halophiles Thermoacidophiles

7. Methanogens  Metanogens are able to reduce CO 2 into methane (CH 4 ).  They die if exposed to oxygen.  They produce marsh gas as bubbles in stagnant water.  They are also present in the gut of cattle and termites, since there is no oxygen there.  Methanogens are rod shaped or spherical.

8. Halophiles  Halophiles are bacteria that can survive in extremely salty environments (up to 10 times more concentrated than the amount of salt in the ocean.  They contain bacteriorhodopsin, a red or orange pigment.

9. Thermoacidophiles  The thermoacidophiles are organisms that can survive in extremely high temperatures and low pH.  They can survive in 100° Celsius with a pH of 2.  Most of these organisms are anaerobic in nature.

10. Kingdom – Eubacteria Cyanobacteria Contain chlorophyll (they can make their own food) No flagella Spirochetes Have a flagella so they can move Some cause very dangerous diseases Proteotic Bacteria Move with either a flagella or by gliding Some are helpful while others are harmful.

11. Eubacteria (true Bacteria) Some eubacteria are considered as helpful bacteria. For instance, lactobacillus helps in the formation of curd. There are many which help in the making cheese and pickles. Nitrogen fixing eubacteria helps in the process of nitrogen fixation. They live in almost everywhere. Some eubacteria are harmful and can cause meningitis, cholera, typhus, lyme's, salmonellosis, tetanus, tuberculosis, etc. Some of the eubacteria examples are Bacillus anthracis, Escherichia coli, Clostridium perfringens, Clostridium tetani, etc.

12. Eubacteria (true Bacteria) Can also be classified by their three main shapes: –Cocci (round) –Baccilli (rod shaped) –Spirulla (spiral shaped)

13. Kingdom - Protista Unicellular (only 1 cell big) They have a true nucleus (eukaryotic) Some behave more like plants, others are more like animals.

17. The Euglena

18. Kingdom - Fungi Non-motile (they can’t move) They are heterotrophs (can’t make their own food) They absorb food from dead material.

19. Kingdom - Plantae Unicellular (e.g. phytoplankton) and Multicellular (e.g. trees) Autotrophs (can carry out photosynthesis to make their own food). Generally stationary (except for the plankton)

20. Kingdom - Plantae

21. Kingdom - Animalia Eukaryotic Multicellular Heterotrophs (can’t make own food) Most can move from place to place

22. Kingdom - Animalia
