Oligotrophic have a low number of plants and animals making it very blue and able to see through it.
Mesotrophic have a normal or average number of plants and animals giving it a somewhat greener appearance.
Eutrophic have a large number and variety of plants and animals, also, a large amount of nutrient giving the lake a thick green color.


As lakes and ponds get older the number of species increase. Ecological succession is change so this is how these ponds are related to this. I would describe my tank as oligotrophic because there is maybe two types of plants in it and a turtle.
