What are characteristics of freshwater biomes?
Freshwater habitats include the still waters of lakes and ponds and the flowing waters of rivers and streams. Lakes and ponds vary tremendously in size and and in biodiversity. The can all be divided into 3 major zones: the littoral zone is relatively warms because of uts exposure to sunlight. Organisms living the littoral zone invlude photosynthetic plants and algae, insects, mollusks, crustaceans, fishes, amphibians, ducks, and turtles. The limnetic zone includes habitts that are close to the water surface but far from shore. Its occupied largely by plankton. Phytoplankton are photosynthesizing plankton, whereas zooplankton are heterotrophic planton. Fish may also be found in the limnetc zone. The profundal zone describes deep water habitats in ponds and lakes.
