This document discusses aquatic microbiology, including the study of microorganisms found in marine and freshwater ecosystems. It describes different types of microorganisms commonly found in water such as bacteria, viruses, protozoa, algae, and fungi. Many of these microbes can cause diseases in humans, like gastrointestinal illnesses from eating contaminated food or water. The document also outlines various treatment methods used to remove pathogens and contaminants from drinking water to make it safe for human consumption.

5. (1) Marine Ecosystem

plants and animals interact with the chemical
and physical features of the environment.
 aquatic
areas of life, They can be oceans, ponds
, marshes, lagoons, or any area with water that
supports life.

6. (2) Fresh Water Ecosystem

factors, including temperature , light
penetration, and vegetation.

Only 3% of the world's

99% of this is either frozen in glaciers and
pack ice or is buried in aquifers.

The remainder is found in lakes, ponds, rivers,
and streams.

7. wide and includes the habitats like
 Planktons

live in water column
 incapable of swimming
 crucial source of food to
large aquatic organisms, such as fish and whales.


Benthos
community of organisms which live on, in,
or near the seabed
 also used in freshwater biology
 food sources for the benthos are algae
 Organisms such as sea stars, oysters,clams,
sea cucumbers, brittle stars

mainly bacteria and archaea.
Temp from –40°C to 120°C
industrial uses for water treatment
and for cleaning up pollution.
 Biofilm
group of microorganisms in which
cells stick to each other on a surface.
