ENV/100 October 29, 2012 Shelby Barker Rainforest Rainforest covers about 6% of the earth's surface and is one of the most diverse ecosystems. Influencing how energy flows through this ecosystem is the fact that most f the plants living mass is above ground. There are plenty of cycle in the rainforest that make sure the flow of energy and nutrients through this ecosystem is continual. Photosynthesis is the process which energy is harnessed from the sun and used along with carbon dioxide and

culture type. For example, Streptococcus agalactiae, also known as Group B Strep or GBS, is a normal flora of the digestive, urinary, and genital tracts, that is found in 20 - 40% of women. While it usually causes no illness in carriers of the bacteria, a pregnant woman colonized with GBS late in her pregnancy can pass it to her baby with very serious outcomes. Newborn GBS most often infects the lungs, blood , and spinal fluid, causing pneumonia, sepsis, and meningitis, respectively. (ACOG, 2014)

Bugs, bugs, bugs! Bugs are everywhere in our environment. The potential for infection never ends! The spread of infection is dependent upon three key factors. Pathogenic organisms, those that cause infection, require a source or home where they thrive, a means of transmission, and a susceptible host to be successful. The source of an infecting organisms is classified as endogenous or exogenous. Endogenous infections are caused by microorganisms that naturally inhabit the human body. These organisms

Growth of Microorganisms Culturing is the growing of micro-organisms in prepared media in the laboratory. The prepared medium is called the ‘culture medium’. Bacteria, fungi and algae grow easily in test-tubes, flasks or Petri dishes of culture media. Virus on the other hand, can only grow and multiply inside living cells, so they cannot be grown in a culture medium. Micro-organisms are able to increase in size and multiply in number of cells. The growth of micro-organisms is measured based on
