| Description: Lakes and ponds are bodies of open, standing water Littoral zone = region ringing the edge of a water body Benthic zone = extends along the entire bottom of the water body Home to many invertebrates Limnetic zone = open portions of the lake or pond where the sunlight penetrates the shallow waters Profundal zone = water that sunlight does not reach Supports fewer animals because there is less oxygen Oligotrophic lakes and ponds = have low nutrient and high oxygen conditions Eutrophic lakes and ponds = have high nutrient and low oxygen conditions Eventually, water bodies fill completely in through the process of succession Inland freshwater seas = large lakes that hold so much water, their biota is adapted to open water Picture Stats: Views: 1814 Filesize: 197.94kB Height: 903 Width: 1390 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=35829 |
