Biodiversity's Role in Ecosystem Resilience and Health

The video discusses the 1988 Yellowstone fire and how biodiversity helped the ecosystem recover. Biodiversity, defined as the variety of life in an area, is crucial for ecosystem health. The video uses a business analogy to explain how diversity aids adaptability. It breaks down biodiversity into genetic, species, and ecosystem diversity, providing examples like beetles and dogs for genetic diversity. The video concludes by highlighting the importance of biodiversity for ecosystem resilience and health, noting that biodiversity is greater near the equator.

What event in 1988 demonstrated the resilience of Yellowstone's ecosystem?

• A volcanic eruption

• A massive flood

• A widespread fire

• An earthquake

How is biodiversity similar to having a variety of products in a business?

• It makes the ecosystem more vulnerable

• It limits the ecosystem's adaptability

• It increases the ecosystem's resilience

• It decreases the ecosystem's health

Which of the following is NOT a type of biodiversity?

• Genetic diversity

• Species diversity

• Ecosystem diversity

• Climate diversity

What does genetic diversity refer to?

• The variety of climates in an area

• The number of species in a community

• The variety of genes within a population

• The number of ecosystems in a region

Why is genetic diversity important for species survival?

• It reduces the number of species

• It limits the adaptability of species

• It decreases the health of the ecosystem

• It increases the odds of survival as ecosystems change

Which of the following is an example of genetic diversity?

• Different climates in a region

• Different dog breeds

• Variety of species in a rainforest

• Number of lakes in an area

What is species diversity?

• The variety of ecosystems in a region

• The number of different genes in a population

• The number of different species and their abundance in a community

• The number of abiotic factors in an ecosystem

Which environment is likely to have high ecosystem diversity?

• Urban areas

• Rainforests

• Polar regions

• Deserts

How does biodiversity generally change as you move away from the equator?

• It fluctuates randomly

• It decreases

• It increases

• It remains constant

What is the relationship between biodiversity and ecosystem health?

• As biodiversity increases, ecosystem health decreases

• As biodiversity increases, ecosystem health remains the same

• Biodiversity and ecosystem health are unrelated

• As biodiversity increases, ecosystem health increases
