Wildfire Prevention and Ecosystem Interactions

The video features Joan Cartan-Hansen hosting a discussion on Idaho ecosystems at the Idaho Museum of Natural History. Experts Rosemary Smith and Leif Tapanila answer student questions about the types of ecosystems in Idaho, wildfire prevention, ecosystem functioning, complexity, invasive species, and desert ecosystems. They also discuss the basic needs of animals and offer conservation tips. The show concludes with a thank you to the guests and an invitation to explore more on the Science Trek website.

What is the primary focus of the Science Trek web show?

• Cooking recipes

• Historical events

• Idaho ecosystems

• Space exploration

Which is the largest ecosystem in Idaho?

• Riparian

• Alpine

• Coniferous forests

• Palouse grassland

What is a natural cause of wildfires?

• Lightning

• Human negligence

• Earthquakes

• Volcanic eruptions

How can we help prevent wildfires around our homes?

• Build larger houses

• Use more water

• Reduce plant life near houses

• Plant more trees

What is a key component of ecosystem interactions?

• Only living organisms

• Only nonliving components

• Interactions between different planets

• Interactions between living and nonliving components

How do plants contribute to ecosystems?

• By consuming other plants

• By taking up nutrients from the soil

• By creating deserts

• By producing oxygen only

Why is it difficult to measure ecosystem complexity?

• Lack of technology

• Too many variables

• Ecosystems are simple

• No interest in research

Can we completely eliminate invasive species?

• No, they are too powerful

• Yes, with enough effort

• No, but we can limit their spread

• Yes, by using chemicals

What is one way to conserve resources to protect ecosystems?

• Conserve water

• Increase food waste

• Use more fossil fuels

• Build more factories

Why do animals need food, shelter, and water?

• To become extinct

• To look good

• To travel long distances

• To survive and reproduce
