What organisms are the most numerous in soils? - Bacteria
What organisms have the greatest biomass? - Fungi
What is the difference between aerobic and anaerobic heterotrophs? - Aerobic use oxygen as electron
acceptors. Anaerobic use nitrogen, sulfur, ironto accept electrons.
How do aerobic conditions influence the decomposition of organic matter? - Decomp is rapid due to
efficiency of aerobic metabolism
How do anaerobic conditions influence the decomposition of organic matter? - Decomp is slowed,
because anaerobic respiration is slower and produces less energy
How did the Everglades get high levels of organic materials build up? - The Everglades is historically
flooded, so organic matter decomp is slowed when is submerged in water and not in oxygen. Then the
input of new OM exceeds losses and leads to a vast amount of organic matter accumulation.
How do the basics of the historical flow regime in the Everglades compared to today? - Historically the
Everglades started at the Kissimmee Basin and a floodplain river pushed water into Lake Okeechobbee.
The water then went down south until it reached the area around the keys. Today much of the
Everglades has been drained and levees and canals push water from Okeechobee east out into the
Atlantic.
Where is EAA and what is it? - Everglades Agricultural Area, which is mainly devoted to sugarcane with
smaller areas used for vegetables, sod, citrus, and rice. It is the area southeast of Lake Okeechobe
How were soils subsequently lost to subsidence in the EAA region? - The drainage exposes soils to
oxygen, which causes them to decompose more efficiently.
What are the three primary macronutrients? - Nitrogen, phosphorous, potassium
