23
Q

in dealing w/ the Hydrosphere (water), what is 2 genus’ of bacteria whose habitat is water?

A

pseudomonas (they also are salt-tolerant)

vibrio

24
Q

in dealing with the Lithosphere (land), how is Nitrogen captured in association w/ the roots of legumes?

A
  • bacteria Rhizobia infects the roots

- causes the formation of special nitrogen fixing organs called Root Nodules

25

what draws CO2 out of the atmosphere

A

photosynthesis

then decomposed by ? (2 ex.)

A

m/o

fungi & bacteria

29

A

producers
consumers
decomposers

31
Q

(3) composites of abiotic protion

A

mineral particles
water
atmospheric gas

32
Q

what is a dynamic ecosystem

A

soil

33
Q

the composition of the lithosphere (land)

A

soil microbiology

34
Q

eutrophicaiton: water is nutrient ______ by oligotrophic

what is a way to determine the number of an indicator m/o in a volume of water??

A

standard plate count

incubate colonies

38
Q

algae can infect shellfish is that a threat to humans?
