Ecosystem Dynamics and Resilience in Coral Reefs and Beyond

Paul Anderson discusses ecosystem dynamics, focusing on how disruptions affect ecosystems like coral reefs. He explains natural and human-caused disruptions, such as pollution and invasive species, and how organisms adapt to environmental changes. The video includes a historical example of the Irish Potato Famine to illustrate the importance of biodiversity. It concludes with a teaching progression for understanding ecosystems from elementary to high school.

What is a key component of an ecosystem like a coral reef?

• Both living organisms and non-living materials

• Only living organisms

• Only non-living materials

• Only plants

Which of the following is an example of a natural disruption to an ecosystem?

• Deforestation

• Invasive species

• Pollution

• Lava flow

How does the lynx adapt to its cold environment?

• By migrating south

• By changing its fur color

• By having big feet to run on snow

• By having large ears

What was a major consequence of the Irish Potato Famine?

• Introduction of new species

• Decrease in population

• Improved agricultural practices

• Increase in biodiversity

What does biodiversity refer to in an ecosystem?

• The temperature range

• The amount of water

• The variety of species

• The number of plants

In lower elementary grades, what should students learn about plants and animals?

• They can survive without water

• They require specific environmental conditions

• They are not affected by temperature changes

• They can live anywhere

What is a sign of a healthy ecosystem?

• Stable temperature

• High biodiversity

• Low biodiversity

• No animal migration

What happens to ecosystems when they face too rapid changes?

• They become more stable

• They adapt immediately

• They may not cope well

• They increase in biodiversity

What is the focus of teaching about ecosystems in middle school?

• Only animal life in ecosystems

• Only plant life in ecosystems

• Dynamic and changing nature of ecosystems

• Static nature of ecosystems

Why is biodiversity important for ecosystem stability?

• It reduces the number of species

• It helps ecosystems respond to changes

• It increases the temperature

• It limits the growth of plants
