What are the two main types of aquatic biomes?

Back

The two main types of aquatic biomes are freshwater biomes (like lakes, rivers, and wetlands) and marine biomes (like oceans, coral reefs, and estuaries).

Define the benthic zone in aquatic ecosystems.

Back

The benthic zone is the lowest ecological zone in a body of water, consisting of the sediment surface and sub-surface layers, where organisms like clams and worms live.

Front

What is dissolved oxygen and why is it important in aquatic ecosystems?

Back

Dissolved oxygen is the amount of oxygen that is present in water, essential for the survival of aquatic organisms such as fish and invertebrates.

What are nekton?

Back

Nekton are actively swimming aquatic organisms, such as fish and whales, that can move against currents.

What are benthos?

Back

Benthos are organisms that live on or in the bottom sediments of aquatic environments, including clams, worms, and other invertebrates.
