Definition
| (multiple) species + environment |
|
|
Term
| Two keys for every environment we discuss |
|
Definition
1. why are microbes there?
2. Nothing in real environment is in a pure culture/isolated/ always interacting |
|
|
Term

|
|
Term

|
Definition
| Ideal temps, salt, pH, found a niche (nutrients vs competiton), Genome- use of O2, nutrient req, |

|
Definition
living organisms
all organic material- CHPN macromolecules |
|
|
Term
-- organisms participate in food webs
Food web- |
|

All
Energy (atp cycling) and materials (organic /inorganic for biomass) |
|
|
Term
|
Definition
|
|
Term
|
Definition
Acquire all elements to build into cells (anabolism=biosynthesis)
Growing cells need carbon |
|
|
Term
|
Definition
| breakdown of organc nutrients to inorganics (catabolism) |
|
|
Term
Primary producers-
2 jobs-
-troph |
|
Definition
absorb outside energy
assimilate inorganics into biomass
photo auto troph |
|
|
Term
|
Definition
| cyanobacteria- anabaena spiroides or prochloroccus |
|
|
Term
consumers are -troph
3 types: |
|
Definition
chemo hetero troph
Grazers
predators
decomposers |
|
|
Term
|
Definition
| protists (euk) viruses (phage) |
|
|
Term
| At every level of energy you only get -% of biomass formed. What happens to the -%? |
|
Definition
10%
90% energy is lost as heat- ETC and forming CO2 from producer to consumers |
|
|
Term

|
Definition
|
|
Term
| Three classes of Symbiosis |
|
Definition
mutalism
commensalism
parasitism |
|
|
Term
|
Definition

good thing
one dies w/out other |
|
|
Term
|
Definition
| one species benefits other is neutral |
|
|
Term
|
Definition
| one species benefits harming the other |

Term
| Termite gut has what type of symbiosis? |
|
Definition
|
|
Term
| Protist inside terminte gut? |
|
Definition
|
|
Term
| Releationship between protist and termite is called |
|
Definition
| syntrophy (eating together) |
|
|
Term
| Mixotricha paradoxa has what other microbes? |
|
Definition
spirochetes
anchor bacteria
bacterial endosymbionts
vestigial endosymbionts |
|
|
Term
| Spirochetes in mixotricha paradox are: |
|
Definition
large and small
help with motility and move protist around protist gut |
|
|
Term
|
Definition
| unknown function. sit on outside of protist |
|
|
Term
|
Definition
digest cellulose
cannot survive outside the protists |
|
|
Term
|
Definition
| "organelles" lost even more function than endosymbionts |
|
|
Term
bacterial endosymbionts digest wood/cellulse to form-- which is absorbed by --
overall eqn: |
|
Definition
acids= formic, lactic acid, acetic
termite, benifit
Cellulse-> H2 +CO2 |
|
|
Term
|
Definition
| outside protist/inside gut |
|
|
Term
| Methanogens take - from - and turn it into - |
|
Definition
| CO2 +H2 from protist->CH4 |
|
|
Term
| What does the termite do with acetate? |
|
Definition
Krebs cycle linked with respiration
Termite can get ATP from acetate -> CO2 |
