Aquatic Ecosystems Exit ticket

What are the two main types of aquatic ecosystems?

• Desert and tundra ecosystems

• Forest and grassland ecosystems

• Urban and suburban ecosystems

• Freshwater and marine ecosystems

What is the primary difference between freshwater and marine ecosystems?

• Temperature

• Depth of water

• Type of plants

• Salt content

What are some examples of freshwater ecosystems?

• Lakes, rivers, ponds, and wetlands

• Mountains and forests

• Oceans and seas

• Deserts and tundras

What are the characteristics of coral reef ecosystems?

• Low biodiversity, simple food webs, and competitive relationships between corals and algae

• Moderate biodiversity, linear food chains, and neutral relationships between corals and algae

• No biodiversity, no food webs, and parasitic relationships between corals and algae

• High biodiversity, complex food webs, and symbiotic relationships between corals and algae

What are the major threats to coral reef ecosystems?

• Deforestation and habitat destruction

• The major threats to coral reef ecosystems include climate change, overfishing, pollution, and ocean acidification.

• Excessive conservation efforts

• Decrease in water temperature

How do human activities impact aquatic ecosystems?

• Reducing carbon emissions

• Planting more trees

• Pollution, overfishing, and habitat destruction

• Building more dams

What is overfishing and how does it affect aquatic ecosystems?

• Overfishing is the act of catching too many fish at once, which can lead to the depletion of certain fish species and disrupt the balance of the aquatic ecosystem.

• Overfishing is the act of catching too many fish at once, but it has no impact on aquatic ecosystems.

• Overfishing is the act of releasing too many fish into the aquatic ecosystem, which helps in maintaining the balance.

• Overfishing is the act of introducing new fish species into the aquatic ecosystem, which improves biodiversity.

What are invasive species and how do they threaten aquatic ecosystems?

• Invasive species are non-native organisms that help native species thrive and coexist peacefully. They have no negative impact on aquatic ecosystems.

• Invasive species are non-native organisms that have no impact on the environment, economy, or human health. They do not threaten aquatic ecosystems in any way.

• Invasive species are non-native organisms that cause harm to the environment, economy, or human health. They threaten aquatic ecosystems by outcompeting native species, disrupting food chains, and altering habitats.

• Invasive species are native organisms that benefit the environment and human health. They threaten aquatic ecosystems by promoting biodiversity and improving habitats.

What are some conservation efforts to preserve aquatic ecosystems?

• Reducing pollution, protecting habitats, implementing sustainable fishing practices, and creating marine protected areas

• Building more factories near water bodies

• Allowing unrestricted fishing

• Clearing natural habitats for urban development

Area in a body of water where it is cool and dark and bottom-feeders are located.

• Littoral Zone

• Benthic Zone

• Limnetic Zone
