humans sweat to remove water and active transport.
Get rid of the body wastes.
phagocytes engulf and then digest the microorganisms to get rid of them.
Water just diffuses ( called osmosis ) across their cell membranes down it's concentration gradient. So much so that some single celled organisms need contractile vacuoles to get rid of the excess water so they do not become hypotonic in condition.
The water moistens the organisms.
Single-celled organisms get rid of waste by first creating pockets of air around the waste material. Then they eject these air pockets, waste and all.
You can't get rid of extra water in the washer.
If you mean organisms that live in water, then that will affect the ecosystem because some organisms won't have the dead organisms that they used to feed on, which will cause their death. On the other hand, if you mean the death of organisms that live on land in water, then that will affect the water, and will probably make it contaminated, which will cause the death of the organisms that drink the contaminated water.
No, but all organisms rid theirselves of waste in some manner.
Organisms were first created in the water because the earth's land was never created yet. Water organisms have been the first organisms on earth and it says so in the begining of the bible too. Organisms were created in water because there was no land yet for them to be created on.
