The saltwater biome is a water biome that has a high salt content
The saltwater biome is the largest of all the earth's biome.
- it can be divided into three zones:
- Shallow Ocean Zone
- Ocean Surface Zone
- Deep Ocean Zone
- The shallow ocean zone along the coasts makes up only a small part of the saltwater biome.
- Sunlight reaches the sea bottom in this zone, and the water temperature remains relatively constant
- Sunlight penetrates the top few hundred meters of the ocean surface zone. Here, photosynthesizing plankton are the primary producers; consumers include tuna, sharks, whales, and ocean birds.
- Plankton are microscopic, free floating organisms that serve as food for larger organisms.
- The deep ocean zone consists of everything deeper than 100 meters.
- Too little sunlight penetrates the cold waters of the deep ocean zone to support photosynthetic organisms.
- those with standing water, such as lakes and ponds
- those with flowing water, such as rivers and streams
- Lakes are usually larger and deeper than ponds and may be deep enough to have a colder, deeper layer that receives little or no sunlight.
- Most organisms live in the upper, sunnier part of the lake.
- Producers include floating and shallow-water plants.
- Consumers include fish, insects, frogs, beavers, and birds.
- Decomposers live at the bottom of the lake.
- Rivers and streams have moving water.
- The quick flow of water oxygen to the water, which allows certain organisms such as trout to live there.
- Insect larvae, algae, and worms live on rocks in the streams.
- Water in an estuary is usually warmer than ocean water and contains less salt.
- Salt content changes with tides; During high tides, more ocean water flows in, so the water is saltier than when the tide is out.
- Estuaries are important breeding grounds for fish, shellfish, and birds.
- Fish and shellfish release their eggs in estuaries because there is plenty of plankton available on which the hatchlings can feed.
- Migratory birds such as geese and ducks rest and feed in estuaries.
