Aquatic Biomes

Front

What are aquatic biomes?

Back

Aquatic biomes are ecosystems found in water environments, including freshwater (like rivers and lakes) and marine (like oceans and estuaries) ecosystems.

Front

What factors influence ocean currents?

Back

Ocean currents are influenced by temperature differences, gravity, wind, and density differences.

Front

What is the average salinity level of ocean water?

Back

The average salinity level of ocean water is approximately 35 parts per thousand (ppt).

Front

Why are estuaries important ecosystems?

Back

Estuaries are important because they are highly productive ecosystems that receive nutrients from rivers, supporting diverse wildlife.

Front

What happens to cold, salty water in the ocean?

Back

Cold, salty water is denser and tends to sink in the ocean.

Front

What is the significance of salinity in aquatic ecosystems?

Back

Salinity affects the types of organisms that can live in an aquatic ecosystem and influences their physiological processes.

Front

What adaptations do organisms in estuaries have?

Back

Organisms in estuaries must tolerate wide ranges of temperature and salinity due to fluctuating environmental conditions.

Front

What is the difference between freshwater and marine biomes?

Back

Freshwater biomes have low salt concentrations (less than 1%), while marine biomes, like oceans, have higher salt concentrations.

Front

How do temperature and salinity affect water density?

Back

Colder water and water with higher salinity are denser than warmer, less salty water.

Front

What role do wetlands play in aquatic ecosystems?

Back

Wetlands act as natural filters, improve water quality, and provide habitat for many species.
