What is the plankton network?

plankton net is a device that can be used to catch plankton (small plants and animals that live in the ocean). Scientists use special plankton networks with high volumes, but anyone can make a plankton net by binding the foot pantyhose at the end of the metal ring. It can be immersed in water from a slow -moving ship to collect plankton for observation under the microscope. Continue to drag the plankton net until it is clear that many small pieces of organic material are captured. That's plankton.

plankton exist everywhere in the pelagic (illuminated) zone of the ocean, but in most places there are relatively low concentrations, which requires the plankton network to concentrate for observation. The plankton you probably catch will be small, usually a diameter or less by 2 mm, so you need a magnifying glass or even better, a microscope to display them. Plankton lives only a few days after you remove it from the ocean splankton net so bYou should have a quick look at it. It can be maintained a little longer by putting it in the refrigerator. If you want to preserve planktonic organisms after a while die, add alcohol to seawater, so it becomes 70% alcohol.

Some of the organisms you can find using a plankton network include braopepods (1-2 mm crustaceans), amphipodes (slightly larger shrimp crustaceans), tunings (bag filter feeders), cords ("water flea"), ostravas ("seed" ("seed" ("seed" ("Saézové", Sharp ", O-SEMEN (" seed ", o-serlene", and about the seed "seeds", o-anxis ", and to the ozaches (" seed "and pieces of algae. If you have a stronger microscope, you can see the smallest planktonic organisms, including rotifers and various larvae larvae.

plankton is involved in bust and boom cycles, where their number increases rapidly in warmer weather and drop in colder weather. It is pRoto that their final source of food, eyelashes are very sensitive to environmental conditions. The largest plankton is ideal in the tropics where the temperature and level of nutrients are ideal.
