Why is filtration an important part of water treatment?
They are exposed to a greater variety of contaminants
It is an area where all the water drains into a river ending in the ocean near Cape Fear.
Filtration removes small particles from the water.
Some organisms would adapt to the new pH, while others that could not, would die.
oxygen
reducing use of fertilizers near the stream
The freshwater is closer to the surface than the saltwater
Hydrothermal vents give off life-sustaining chemicals and have huge biological communities
