Ecosystem Feedback Mechanisms and Kelp Forests

Front

What is a keystone species?

Back

A species that helps to hold an ecosystem together.

Front

What happens when urchin populations are allowed to grow uncontrolled?

Back

Urchins can destroy all of the kelp, leading to 'urchin barrens.'

Front

What type of species are sea otters in relation to sea urchins?

Front

What is the main function of feedback mechanisms in an ecosystem?

Back

To keep the numbers and types of organisms relatively constant.

Front

What organisms return nutrients to ecosystems?

Back

Decomposers.

Front

What role do producers play in an ecosystem?

Back

Producers create energy through photosynthesis.

Front

How do consumers interact with producers?

Back

Consumers eat producers for energy.

Front

What is the impact of removing a keystone species from an ecosystem?

Back

It can lead to significant changes and potential collapse of the ecosystem.

Front

What is an example of a feedback mechanism in ecosystems?

Back

Predator-prey relationships that regulate population sizes.

Front

What is the relationship between kelp forests and biodiversity?

Back

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