Kelp Forest Ecosystem

Front

What happens when otters are removed from a kelp forest ecosystem?

Back

The urchin population rises, the kelp population drops, and the kelp gets eaten more quickly than it can regrow.

Front

Which factor does NOT limit the growth of kelp forests?

Back

Salinity does not limit the growth of kelp forests.

Front

What is a keystone species in a kelp forest?

Back

A keystone species is one that has a disproportionately large effect on its environment relative to its abundance. In kelp forests, sea otters, kelp, and sea urchins are all considered keystone species.

Front

What provides support and height to the leaf-like structures of seaweed?

Back

The stipe provides support and height to the leaf-like structures of seaweed.

Front

What is the function of the blade in kelp?

Back

The blade is the leaf-like structure of kelp that captures sunlight for photosynthesis.

Front

What is the holdfast in a kelp forest?

Back

The holdfast is the root-like structure that anchors kelp to the ocean floor.

Front

What role do sea urchins play in a kelp forest ecosystem?

Back

Sea urchins are herbivores that feed on kelp, and their population can significantly impact kelp forest health.

Front

How does light affect the growth of kelp forests?

Back

Light is essential for photosynthesis, and insufficient light can limit the growth of kelp.

Front

What is a pneumatocyst in kelp?

Back

A pneumatocyst is a gas-filled bladder that helps kelp float and stay upright in the water.

Front

Why are kelp forests important to marine ecosystems?

Back

Kelp forests provide habitat, food, and shelter for a diverse range of marine species.
