A. lumbricoides (worms)

Question 11

List the pros that microbes make in the lives of humans:

Answer 11

• Digestion
• Food Production
• Biosphere (oxygen production/nitrogen fixation)
• Protection (by competing with each other)
• Biotech- used to make medicines
• Bioremediateion- can survive in toxic environments and thus detoxify

Question 12

Lists the cons that microbes make in the lives of humans

Answer 12

• Disease. Play a major role in morbidity and mortality over the course of human history
• Involved in food spoilage (Decomposers)

Question 13

How do microbes work on the biosphere?

Answer 13

• o2 production through photosynthesis

- nutrient cycling- Co2 and N fixation

Question 14

What is a detrivore?

Answer 14

Decomposer

Question 15

Describe microbes’ role in Nitrogen Fixation

Answer 15

Bacteria produce NH4 (ammonium), which plants use

Concert N to N2 to NH3 (ammonia) then finally to NH4 (ammonium)

Plants then use ammonium

Question 16

How do you classify micro-organisms?

Answer 16

Through genes (RNA)
