From rainfall

Via underground springs

1

Which factor determines how much life a river can support?

Amount of Oxygen

River width

Water flow speed

Distance from the sea

1

Why is dissolved oxygen important for organisms in a river ecosystem?

Provides buoyancy

Helps in digestion

Necessary for respiration

1

What distinguishes a lake from a pond?

Lake has salt water

Pond is larger and deeper

Pond has more aquatic life

Lake is typically larger and deeper than a pond

1

How does depth affect temperature in a lake?

Depth has no impact on temperature

Deeper water is always warmer

There's no temperature difference

Deeper water is usually colder

1

1

Why do marshes play an important role in the ecosystem?

They produce large quantities of oxygen

They act as a natural water filter

They are the main source of freshwater

They prevent desertification

1

What is an estuary?
