variable environment aerobic respiration is the release of energy withoxygen

it is crucial that marine organisms Anaerobic respiration is the release of energy without

thesethreefactors change of respiration when there is a low oxygenconcentration
surface area us volume ratio is calculated by surface area volume As the size of the organism
increases the surface area decreases incomparisonto the volume small organisms tend to have a larger
surface area than volume Largerorganisms have largervolumes than surfacearea Diffusion is movingparticles
froma higherconcentration to a lower concentration Diffusion in small organisms is a quick and sufficient
process However in largeorganisms diffusion is too slow In order for diffusion to work organisms flatten
themselves to increasetheirsurface area or they use specializedexchangesurfacessuchas lungsor gills

Osmoregulators are marine organismswho have a
different water and ion content inside their
bodiescomparedto theenvironmentsurroundingthem
Osmoconformers are organisms that have the
same internal water and ioncontentas there is in
the environmentsurroundingthem Most osmocon
formers tend to be stenohaline invertebrates
Stenohaline means organisms that are able to
tolerate a small rangeof salinities On the other
hand euryhaline are organisms that are able to
tolerate a largerange ofsalinities therefore
they have more flexible options of where they
couldpossibly live
