Conservation biologists apply these data to preserve species and restore environments. 50. 2: each year, lakes experience fall and spring turnovers, which redistribute freshwater nutrients as well as oxygen. (fig. 50. 4a: in pure seawater, the total amount of light available at a depth of. 10 m is less than 40% of the amount available at the surface, and virtually no light reaches depths greater than 40 m. (fig. 50. 4b: freshwater environments: lakes and ponds, ponds are small, while lakes are big enough that the water in them can be mixed by the wind, biologists describe the structure of lakes and ponds by naming five zones: (fig. Freeman, biological science, 4e, chapter 50: bogs develop depressions where water flow is low or nonexistent.
