What are the abiotic factors that affect aquatic ecosystems?

Back

Light, salinity, temperature.

Front

Why does photosynthesis not occur in the deep ocean?

Back

Because sunlight does not penetrate.

Front

Front

What is salinity and why is it important in aquatic ecosystems?

Back

Salinity is the concentration of salts in water, and it affects the types of organisms that can thrive in different aquatic environments.

Front

What is the significance of temperature in aquatic ecosystems?
