Which characteristic of aquatic biomes affects how much sunlight can reach plants below the surface?

• Salinity

• Depth

• Flow

• Temperature

Why do rapidly moving bodies of water like rivers have high dissolved oxygen levels?

• They are shallow

• They have high salinity

• They facilitate the mixing of air and water

• They have a high temperature

What happens to the dissolved oxygen levels in water as the temperature increases?

• It increases

• It decreases

• It stays the same

• It fluctuates randomly

Which zone of a lake or pond is too deep for sunlight to reach?

• Littoral zone

• Limnetic zone

• Profundal zone

What is a key distinguishing factor of freshwater wetlands?

• Soil submerged or saturated with water for part of the year

• High salinity levels

• Absence of emergent vegetation

• Low nutrient levels
