Microorganisms such as bacteria can be removed by disinfection. Certauns substances called biocides are addes to water to make it pure. Purification can also be done by UV-light .
False, because most organisms decompose fairly quickly after they die. For an organism to be fossilized, the remains usually need to be covered by sediment soon after death. hope this helps :))
I believe the correct answer is upwelling. Lets say we have producers such as plankton. well upwelling currents bring dead matter from the ocean floor up to the surface, creating plankton.
What it eats, what weather it's build for and DNA
