Robert koch and his wife invented agar petri plates. Guild: many species that have the same function. Microorganisms are able to influence their environments; they cause symptoms of sicknesses or cause environments to become anoxic if they use up all the oxygen. Community 1: in the photic zone, there are phototrophs that fix inorganic to organic matter using sunlight. Community 2: in the oxic zone, there are aerobes and facultative aerobes that exploit the organic matter made from community 1. Community 3: in the anoxic zone, there are anaerobes and facultative anaerobes that thrive off the products of community 1 and 2. The first community is the best electron acceptors. Organisms are classified in term of their energy and carbon sources:
