Web of Life
The web of life involves the sequence of the transfer of energy and matter from one organismto another in an ecological community.
What are Bacteria?
• Single-celled organisms
• Invisible to the naked eye
• Live almost everywhere in great numbers
• They are in air, water, soil, and ice.
• They are even inside us!
• In fact, we couldn’t properly digest food without them!
• Without bacteria, plants couldn’t grow, garbage wouldn’t decay, and there would be a lot less oxygen to breathe.
Bacteria and the Human Body
Armpit skin has more than 500,000 bacteria per square inch.
About 70% of nurses wearing artificial fingernails had pathogenic bacteria under their nails, after hand washing compared to 26% of nurses with real nails.
About 10% of the dry weight of a human body is bacteria. About 30 % of all
human feces is bacteria.
Nine of ten cell phones are coated with some kind of bacteria, and 1 in 6 cell phones is contaminated with the bacteria E. coli.

E. coli
Although most strains of E. coli are harmless, their presence is
indicative of fecal contamination, and hence an increased possibility of the presence of more dangerous organisms.
Fecal contamination of water sources is highly prevalent worldwide, accounting for the majority of unsafe drinking water.
In developing countries most sewage is discharged without treatment. Even in developed countries events of sanitary sewer overflow are not uncommon.

Research Project: Examination of bacterial levels in water and sediment for the development of refined monitoring protocols for inland recreational waters
AU Research -2014: Examination of bacterial levels in water and sediment for the development of refined monitoring protocols for inland recreational waters Conclusions:
• E. coli concentrations were sometimes significantly different when sampling the surface
water at different times of the day.
• Both E. coli and Enterobacteriaceae were present in significantly higher numbers in the
sediments than the surface water.
• Although there was no significant correlation between the number of waterfowl observed at each beach and the concentration of E. coli present in the water, Canada goose feces was found to test positive for Salmonella and high levels of E. coli.
GOOD IDEA!
Freshwater Sites = 38
Coastal Sites = 25(ADEM sites)
