Marine Biomes

2 Types of Marine Biomes Freshwater –Rivers and Streams –Lakes and Ponds Saltwater –Ocean –Estuaries

Freshwater Biomes Freshwater contains little or no salt. There are Flowing freshwater = rivers and streams and Still Freshwater = lakes and ponds

Flowing Freshwater –Rivers

Freshwater Ponds –Small, shallow bodies of water –Sunlight penetrates all the way to the bottom –Most completely filled with plant material –Very high amount of nutrients

Freshwater Ponds

Freshwater Lakes –Larger and deeper than ponds –Plant growth is limited to the shoreline –Sunlight does NOT penetrate to the bottom= no plants after a certain depth!

Freshwater Lakes

Saltwater Biomes About 95% of the water on Earth has a high concentration of salt. (High salinity)

Saltwater Estuaries (Wetlands) –Area where a river meets an ocean –Mix of salt and freshwater –Located near coastlines, border land –Extremely fertile –Nutrient levels are higher than both salt and freshwater

Saltwater Estuaries –Chesapeake Bay
