ecology bio 2

oraganic

carbon hydrogen bonds

includes marcomolecules (carbon, lipids)

complex molecules produced by living organisms

inorganic

no carbon EXCEPT CO2

no carbon hydorgen bonds

more simple molecules from nonliving stuff

energy flow: primary producers autotrpohs

self feeder

produce ganic ,olecules from co2

energy flow: consumers

obtain food molecules by eating others

decomposers vs detritivore

decomp: organic to in organic breakdown

detri: smaller pieces of organic matter

who can extract energy from nonliving sources

primary producers

GPP - N = NPP what does r they stand for

GPP: gross primary production every producers make

n: what producer uses

npp: whats left over for consumers

things that can limit productivity in terrestial n aquatic areas

terrestial: temp n mositure

aquatic: nutrients

can decomposer be considered their own tropic lvl?

ya

food web vs food chain

web: better at explaining interactions w more species

energy pyramid

the a,outn of energy that flows through tropic lvls

why is emergy lost through food chaim?

onyl part of it is eaten as they go up so some of it stays down

not all biomass can b digested

only 10% is efficient through food chain

what else is transferred when organisms eat each other

water n nutrients

within abiotic (water cycle)

precipitation

evaporation

run off

infiltration( water to top of soil)

percolation (going deep into soil)

abiotic to biotic water

consumption

absorption

biotic to abiotic water

excretion

death/ decomposition

respriation

transpiration (plants)

which macromolecuke is the backbone of most biological molecules

carbon

what is the largest carbon reservoirs

seeimentary rock which is inorganic until erosion happens

what are the 6 carbon reservoirs

1) sedimentary: inactive needs erosion

2) ocean : actuve n most useable

3) atmosphere: active n mostly co2

4) living organisms: inactive till we die

5)organic molecule in soil (dead decaying matter)

6) fossil fuels:: we cant have ts upif not for human intervention. NOT natural in global c cycle

carbon cycle within abiotic

runoff

volcanic activity

dissolving in water

uplift/ weathering

carbon cycle abiotic to biotic

photosynthesis

carbin cycle within biotic

consumption
