A fish living freshwater would be hyperosmotic to its surroundings. This means that it is surrounded by water that is less salty than its blood. Therefore, the main challenge for Freshwater Fish is to retain enough salt from fresh water for normal bodily functions, resulting in very dilute urine, since they have to get rid of more water relative to salt. A marine fish (salt water fish) has the opposite problem. It is hypoosmotic to its environment, meaning that it lives in water that is saltier than its blood. Therefore, the main challenge for marine fish is to expel enough salt from saltwater to enable it to use the water it takes in for normal bodily functions, resulting in concentrated urine, since they have to get rid of more salt relative to water.
They keep environments relatively stable and maintained between certain limits.
Biotic factors are classified as the living factors in the freshwater stream. These would include the fish, plants, ducks, flies, mosquitoes, etc. The abiotic factors are the nonliving factors in and around the stream. These would include rocks, sunlight, the water itself, etc.
Animals that live in the oceran are called marine animals. Animals that live in water that's not the ocean are called freshwater/aquatic animals.
Hydras are normally living in a fresh-water environment. They can be found in most unpolluted freshwater ponds, lakes and streams in the temperate and tropical regions by gently sweeping a collecting net through weedy areas.
You can find them under rocks, streams, and ponds.
Very, very, very important. Freshwater helps every living organism sustain.
Piranhas are freshwater fish, living in the Amazon basin.Actually they are both freshwater and salt.... Mostly freshwater though!
Trout and Freshwater Crayfish
a sea star is non living
A freshwater organism is any celled living creature that can only survive in fresh(non-salted) water.
Below normal maintenance of an optimal, constant osmotic pressure in the body of a living organism.
An enzyme is one kind of protein that can catalyze a specific reaction whereas a regulatory enzyme is the enzyme which can regulate a series of reaction which undergo in the living organism. So we can say every enzyme is not a regulatory one but the regulatory enzymes are obviously a special kind of enzyme.
No, there is no such living creature known as a Freshwater Plimpy.
