What is an aquatic ecosystem?

• A closed system with no interactions among organisms

• A land-based environment with only plants

• An aquatic ecosystem is a water-based environment where organisms interact with each other and their surroundings.

• A desert ecosystem with no water

Name two types of aquatic ecosystems.

• Tundra ecosystems

• Freshwater ecosystems, Marine ecosystems

• Desert ecosystems

• Urban ecosystems

What role do producers play in aquatic ecosystems?

• Producers consume other organisms for energy.

• Producers inhabit the deepest parts of aquatic ecosystems.

• Producers convert sunlight into energy, forming the base of the food web in aquatic ecosystems.

• Producers are primarily responsible for nutrient recycling.

How do aquatic ecosystems differ from terrestrial ecosystems?

• Aquatic ecosystems are primarily found in deserts and mountains.

• Terrestrial ecosystems have more diverse organisms than aquatic ecosystems.

• Aquatic ecosystems differ from terrestrial ecosystems in their medium (water vs. land), physical and chemical properties, and the types of organisms that inhabit them.

• Aquatic ecosystems are always larger than terrestrial ecosystems.

What are some examples of freshwater ecosystems?

• Oceans

• Deserts

• Coral reefs

• Lakes, rivers, ponds, wetlands, streams

What is the importance of coral reefs in marine ecosystems?

• Coral reefs have no impact on coastal erosion.

• Coral reefs are vital for biodiversity, coastal protection, and supporting marine life.

• Coral reefs are mainly composed of seaweed and algae.

• Coral reefs are primarily used for fishing only.

How do human activities impact aquatic ecosystems?

• Human activities negatively impact aquatic ecosystems by causing pollution, overfishing, habitat destruction, and climate change.

• Human activities only benefit aquatic ecosystems through conservation efforts.

• Aquatic ecosystems are unaffected by human activities.

• Human activities enhance aquatic ecosystems by increasing biodiversity.

What adaptations do fish have for living in water?

• Fish have streamlined bodies, gills, fins, and swim bladders.

• Fish have legs for walking on land.

• Fish have lungs for breathing air.

• Fish have feathers for insulation.

What is the significance of biodiversity in aquatic ecosystems?

• Biodiversity is only important for terrestrial ecosystems.

• Biodiversity decreases competition among species.

• Biodiversity is significant in aquatic ecosystems as it supports resilience, food webs, and water quality.

• Biodiversity has no impact on water temperature.

How do nutrients cycle in aquatic ecosystems?

• Decomposition does not play a role in nutrient cycling in water.

• Nutrients cycle through uptake by producers, decomposition, and recycling in food webs.

• Nutrients are permanently lost from aquatic ecosystems without recycling.

• Nutrients are only absorbed by consumers in aquatic ecosystems.
