Oligotrophic lakes have little nutrients, and therefore do not support much life, whether it be plants or animals.
Mesotrophic lakes have more nutrients than oligotrophic, and therefore support more life and have more plants and animals within them.
Eutrophic lakes have the most nutrients, have turbid waters, and have the highest populations of plants and animals.
The levels of productivity are related to succession because as lakes go through the natural aging process, they will gain more nutrients and become productive and support more life. These terms are helpful in the study of freshwater ecology because knowing that the different levels of productivity have different amounts of nutrients explains why certain fish or plants may or may not be living in one lake and not another. My aquarium would probably be mesotrophic because while it does support life like a plant and the different types of fish it does not just spontaneously start growing other plants, and we have to make sure the conditions and amounts of bacteria and nutrients stay at a healthy level for the fish. Lewisville lake would probably be considered eutrophic.
