contrast in the lake

Postby statesman » Mon Jun 12, 2006 3:52 pm

I read that oligotrophic lakes are generally oxygen-rich but nutrient-poor, and eutrophic lakes are oxygen-poor but nutrient-rich. Why do oxygen and nutrient contrast each other?

because when you have abundant oxygen it means abundant growth of plants and small organisms and the overgrowth is too much, the plants take all the nutrients for themselves so other living things have a hard time living there. I hope this makes sence! A mossy lake is no good because the moss takes over.
