Osmoregulation is how Saltwater Fish breathe in salt water. They can actually live in fresh water, but would be incredibly stressed. The better question would be why cant fresh water fish live in salt. Marine fish evolved to retain and release salts in their body to keep their body salinity level perfect no matter what the water conditions are. Whereas a Freshwater Fish, can not adapt to salt because it takes on the salt threw the gills and can not release its own salinity level to balance. So their bodies literally hemorrhage from the high salt level
Inside dis dick.
organisms in fresh water had to adapt. they first lived in the oceans.
Freshwater microscopic organisms are tiny organisms that live in freshwater environments such as lakes, rivers, and streams. These organisms can include bacteria, algae, protozoa, and microscopic animals like rotifers and zooplankton. They play important roles in the ecosystem by cycling nutrients, serving as food for larger organisms, and contributing to overall water quality.
The amount of nutrients in freshwater will determine what type of organisms there are. If there is bacteria in the water, it may affect the nutrients and contaminate them, which will affect the organisms that live in the water.
Because there is no air, water or living organisms to eat in space but there is on earth.
its because they cant stay together.
No the salmon and bull and sometimes the blue shark swim in freshwater sometimes.
Water voles live near freshwater environments. They do not actually live in the water, but in burrows alongside freshwater sources.
Some examples of freshwater plants include water lilies, hornworts, water hyacinths, and duckweed. These plants play important roles in freshwater ecosystems by providing oxygen, habitat, and food for various aquatic organisms.
its because they cant stay together.
No. Glo fish are freshwater organisms and lobsters are saltwater organisms. And if they could live in the same water, one eats the other.
They can live in both freshwater and salt water but only certain kinds. They only live in waterways with access to the ocean.
