Dissolved 02: In estuaries, prominent plant deaths rob estuaries of oxygen levels. Shallow, well mixed estuaries do much better in oxygen levels.. Unit One. What is a freshwater ecosystem?. Only 3% of the world’s water is fresh.. Freshwater is either frozen in glaciers and pack ice or is buried in aquifers.. The remainder of the water is found in lakes, ponds, streams, and rivers..
