Exploring Estuaries and Chesapeake Bay

What is the significance of biodiversity in Chesapeake Bay?

• Biodiversity is crucial for ecosystem health, water quality, habitat provision, and economic benefits in Chesapeake Bay.

• Biodiversity is irrelevant to the economic activities in the region.

• Biodiversity only affects the aesthetic value of the Bay.

• Biodiversity has no impact on water quality in Chesapeake Bay.

Name three common plant species found in estuarine environments.

• Cacti

• Ferns

• Salt marsh grasses, mangroves, seagrasses

• Pine trees

What are the primary threats to estuarine ecosystems?

• Overpopulation of native species

• Increased tourism activities

• Natural disasters

• Pollution, habitat loss, climate change, invasive species, and overfishing.

How do estuaries contribute to overall ecological health?

• Estuaries have no significant impact on local wildlife or plant life.

• Estuaries contribute to overall ecological health by providing habitats, filtering pollutants, supporting biodiversity, and enhancing nutrient cycling.

• Estuaries primarily serve as recreational areas for fishing and boating.

• Estuaries are mainly important for urban development and construction.

What are the effects of pollution on estuarine habitats?

• Pollution has no impact on food chains in estuarine habitats.

• Pollution improves water quality and promotes biodiversity.

• Pollution only affects terrestrial habitats, not estuaries.

• Pollution degrades water quality, disrupts food chains, harms aquatic life, and leads to loss of biodiversity in estuarine habitats.

Describe one major conservation effort aimed at protecting estuaries.

• Wetlands Protection Act

• Coastal Restoration Initiative

• Marine Mammal Protection Program

• National Estuary Program (NEP)

How do estuaries serve as nurseries for marine life?

• Estuaries serve as nurseries for marine life by providing sheltered environments rich in nutrients and diverse habitats for juvenile species.

• Estuaries are areas where freshwater and saltwater mix, but do not support marine life.

• Estuaries are only important for adult marine species, not juveniles.

• Estuaries are primarily used for commercial fishing activities.

What role do wetlands play in the health of estuaries?

• Wetlands contribute to coastal erosion.

• Wetlands increase salinity levels in estuaries.

• Wetlands improve water quality, provide habitat, and regulate nutrient levels, enhancing the health of estuaries.

• Wetlands have no impact on local wildlife.

Identify a key animal species that relies on Chesapeake Bay's estuaries.

• Blue crab

• Sea turtle

• Oyster

• Striped bass

What impact does climate change have on estuarine ecosystems?

• Climate change increases salinity and improves biodiversity in estuaries.

• Climate change disrupts salinity, temperature, and habitat, impacting biodiversity and ecosystem health in estuaries.

• Climate change leads to more stable habitats and higher fish populations in estuaries.

• Estuarine ecosystems are unaffected by changes in temperature due to climate change.
