Cards

Term
ecosystems
Definition
 all the organisms living in a community AND all the abiotic factors with which they interact
Term
dynamics involve
Definition
energy flow (through) and matter cycling (within)
Term
primary production
Definition
amount of light energy converted to chemicalby autotrophs
Term
limit of solar radiation hitting the earth
Definition
limits the output of producers
Term
NPP
Definition
amount of chemical energy stored in chemical energy and available to consumers
Term
GPP
Definition
total primary production, not all GPP is stored in organic plant material
Term
NPP= GPP- respiration
Definition
NPP= GPP- respiration
Term
primary aquatic producers
Definition
only in the first meter, photic zone
Term
another limit in aquatic
Definition

Definition

essential

determines primary production and decomp.

driven by solar and winds

can go from unavailable to available

cellular respiration and decomp.

Term
nitrogen cycle
Definition

amino acids

plant nurtient

res- atmosphere

processes- nitrogen fixation, ammoniafication, nitrification

 

Term
phosphorus cycle

combustion of fossil fuels is the cause

oxides react with H2O

kills organisms, alters food web

Term
adding toxins
Definition

get stored in fat and increase with biological magnification

greenhouse gases

chlorine is bad
