What is the difference between a lake and a pond?

Back

Lakes are generally larger and deeper than ponds, and they often have different temperatures at various depths, while ponds are shallower and have similar temperatures throughout.

Front

What is an estuary?

Back

An estuary is a coastal area where freshwater from rivers meets and mixes with saltwater from the ocean, creating a unique ecosystem.

Front

What are the main types of aquatic ecosystems?

Back

The main types of aquatic ecosystems are freshwater ecosystems (like lakes and rivers) and marine ecosystems (like oceans and estuaries).

Front

What is the role of sunlight in aquatic ecosystems?

Back

Sunlight is essential for photosynthesis, which allows plants and algae to produce oxygen and food, supporting the entire food web in aquatic ecosystems.

Front

What is a common feature of both estuaries and oceans?

Back

Both estuaries and oceans contain different plants and animals at different depths.

Front

What is the temperature difference in a lake?

Back

In a lake, the temperature can vary greatly with depth, especially in larger lakes, where the surface may be warmer than the deeper layers.

Front

What defines a pond ecosystem?

Back

A pond ecosystem is typically a shallow water body where the temperature is similar at all depths, supporting a variety of plant and animal life.

Front

What is the significance of wetlands?

Back

Wetlands are important ecosystems that filter water, provide habitat for wildlife, and help control flooding.

Front

What is the difference between saltwater and freshwater ecosystems?

Back

Saltwater ecosystems, like oceans, have high salt concentrations, while freshwater ecosystems have low salt concentrations.
