The video discusses the increasing frequency and intensity of wildfires and their impact on ecosystems, particularly aquatic environments. While wildfires can degrade water quality and harm aquatic life, they also offer long-term benefits by creating new habitats. Human interventions, such as firefighting, can sometimes exacerbate ecological issues. The video suggests that controlled burns and strategic fire management can help maintain ecosystem balance, especially in the face of climate change.

What unexpected impact do wildfires have on aquatic ecosystems?

• They increase water temperature.

• They improve water clarity.

• They lead to algal blooms.

• They decrease water levels.

How can debris from wildfires benefit aquatic habitats in the long term?

• By increasing water temperature.

• By creating new habitats and cooler pools.

• By reducing water flow.

• By increasing fish population immediately.

What is a potential negative effect of using chemical fire retardants?

• They reduce algal blooms.

• They improve water quality.

• They increase fish population.

• They can be toxic to aquatic life.

Why might suppressing all wildfires be counterproductive for some fish species?

• It increases water temperature.

• It limits habitat creation.

• It increases water pollution.

• It reduces fish food supply.

What is the benefit of allowing controlled burns in forest management?

• They increase the risk of high-intensity fires.

• They help clear underbrush and prevent larger fires.

• They reduce biodiversity.

• They increase the frequency of wildfires.

How do low-intensity fires contribute to ecosystem diversity?

• By destroying habitats.

• By clearing underbrush and promoting growth.

• By increasing water pollution.

• By reducing fish populations.

What is the main challenge with high-intensity fires in the context of climate change?

• They reduce the frequency of wildfires.

• They demolish ecosystems completely.

• They promote ecosystem diversity.

• They are easier to control.
