Q :what are the characteristics of eubacteria and archeabarcteria ?• A: Eubacteria

- Cell wall of peptidoglycan- can live nearly anywhere- Unicellular-Prokaryotic- Reproduce AsexuallyArchaebacteria- Cell wall without peptidoglycan- Live in environments without oxygen- Prokaryotic- Unicellular-Reproduce Asexually

Q: what are the three ways bacteria are important?• A: in a way some are

producers ,others are decomposers and the rest is used in human use

Q:The 7 diseases caused by bacteria• A: Lyme diseases.• B: Bacteria Meningitis.• C: Tooth Decay.• D: Diphtheria • E: Strep throat • F: Tetanus • G: Tuberculious

Q: what types of environments do bacteria favor?• A: moist and dark area

Q:Describe the structure of a virus • A:A virus is a nucleic acid surrounded by a protein coat,

often a capsid, although their are variables. A virus can invade a cell by injection of the nucleic acid or by invigilation of the cell membrane forming a vacuole. It dismantles the DNA of the cell and reorganizes it into viral particles that may then leave the cell and invade other disease free cells. It may also remain dormant within the cell for some time.

Q:Of What Importance Is A Capsid.• A: The capsid protein contains

proteins that allow the virus to enter the host cell. Without the host cell the virus can not grow/reproduce.

Chapter 3 EcologyKiaya & Adrian

What is the 10% rule?• States that ONLY 10% of energy is

transferred to the next trophic level.

What happens to the other 90%• The other 90% of energy is lost

in body processes and as HEAT to the environment.

= Thermal Energy

food

What is an heterotroph?• An organism that has to get its

own food

• Commensalisms : one benefits and other neutral

• Parasitism : one benefits , other suffer/ harmed
