Osmoregulation is a necessary funtion in order for an organism to regulate the quantity of fluid within its tissues/cells. Without Osmoregulation an organism's fluids may become too concentrated, or too diluted, to carry out normal life functions.
Yes it is since when one excretes, the kidney releases excess water from the excretory system hence osmoregulation takes place.
Osmoregulation is a problem for fresh water Protozoa due to constant influx of water, which they expel by way of contractile vacuole , marine species are mostly osmoconformers .
No, plankton are any microscopic sea-dwelling organisms. these can be plants OR animals. I just checked (April 20, 2011) on Wikipedia: plankton means 'drifter' or 'wanderer' and can be any of the plants or animals UP TO JELLYFISH size. So small shrimp known as 'krill', ARE part of what makes up plankton. Please see the link:
Yes, zooplankton (animal plankton) eats phytoplankton (plant plankton).
Plankton are killed by ozone.
on the surface or the deapest part of the ocean
No.
Plankton are a part of the Kingdom Animalia. The genus and species of plankton can vary greatly because they are a very diverse group of organisms.
Whales primary diet
limnetic
Plankton.
Plankton lives at the very top of lakes, to get optimal amounts of sunlight.
No phytoplankton would have to be plants and dinoflagellates are animals and if regarded as part of the plankton would need to be called zoo-plankton.
No. It is a deep sea fish and not part of the Plankton
