Adaptations of Marsh Plants and Animals

The video explores the tidal salt marsh ecosystem, highlighting its rich plant life due to abundant sunlight, water, and nutrients. It explains photosynthesis and the unique adaptations plants have developed to survive high tides and salt. Key plants like salt marsh cordgrass, spearscale, and salt meadow hay are discussed, along with their ecological roles. The video also covers the impact of invasive species like phragmites and the importance of native plants such as big cordgrass, high tide bush, and red cedar.

What essential process do plants use to convert sunlight into food?

• Transpiration

• Photosynthesis

• Respiration

• Fermentation

What unique condition of the tidal salt marsh requires plants to have special adaptations?

• Extreme cold temperatures

• Constant shade

• High levels of salt and water

• Lack of nutrients

How does salt marsh cordgrass manage the salt it absorbs from the marsh?

• It stores salt in its roots

• It uses salt for photosynthesis

• It secretes salt through its leaves

• It converts salt into sugar

Which animal relies on the roots of salt marsh cordgrass as a food source?

• Fiddler crabs

• Rare skipper butterfly

• Snow geese

• Snails

What is a notable feature of spearscale leaves?

• They are round and flat

• They are needle-like

• They are waxy and thick

• They resemble a spear

What is the primary use of salt meadow hay by marsh animals?

• As a nesting material

• As a food source

• For camouflage

• For building dams

Which plant is crucial for the rare skipper butterfly to lay its eggs?

• High tide bush

• Salt meadow hay

• Big cordgrass

• Phragmites

What is the impact of phragmites in the tidal salt marsh?

• It stabilizes the marsh soil

• It spreads quickly and crowds out native plants

• It provides food for snow geese

• It supports native plant growth

How do the leaves of high tide bush help it survive in drier areas of the marsh?

• They are thin and flexible

• They have a spiky texture

• They are thick and waxy to retain water

• They are broad and flat

What adaptation allows the red cedar to withstand high winds in the marsh?

• Deep roots

• Thick bark

• Small needle-like leaves

• Flexible branches
