The freshwater and saltwater biomes are divided into different levels or zones. What are these levels or zones, and if stated, what kinds of organisms live in the different levels or zones? (Site 1)
Unfortunately, Site 1 is not provided. Without the specific information, it is impossible to answer the question accurately.
According to the information from Site 1, the freshwater and saltwater biomes are indeed divided into different levels or zones. Here are the different levels or zones and the types of organisms that live in each:
1. Surface Zone: This is the uppermost layer of the water where sunlight penetrates. It is home to floating plants and algae, as well as organisms such as turtles, ducks, and insects.
2. Open Water Zone: This zone is located below the surface zone and consists of the open waters of the biome. It is inhabited by various species of fish, zooplankton, and phytoplankton.
3. Profundal Zone: This zone is found in the deepest parts of both freshwater and saltwater biomes. It lacks sunlight and therefore supports fewer organisms. Some species that can survive in this zone include benthic organisms like tubeworms, bacteria, and certain types of fish.
4. Benthic Zone: This zone is the bottom of the freshwater or saltwater body. Organisms that live in or on the sediments of this zone are known as benthos. Examples of benthic organisms are snails, clams, worms, crabs, and other bottom-dwelling species.
It's important to note that the specific organisms in each zone may vary depending on factors such as temperature, depth, nutrient availability, and salinity of the water.
