Exploring The Importance Of Biodiversity In Ecosystems

The video introduces biodiversity, explaining its levels: ecosystem, species, and genetic diversity. It highlights the importance of each level in maintaining healthy ecosystems. The video discusses species richness and evenness, genetic diversity's role in adaptation, and the impact of bottleneck events and inbreeding. It concludes with the concept of ecosystem resilience, emphasizing how biodiversity aids recovery from disturbances.

What is the largest scale of biodiversity?

• Population diversity

• Ecosystem diversity

• Genetic diversity

• Species diversity

How is species richness defined?

• The number of different genes in a population

• The total number of different species in an ecosystem

• The balance of species in an ecosystem

• The number of habitats in an area

What does species evenness measure?

• The number of habitats in an ecosystem

• The distribution of individuals among species

• The genetic variation within a species

• The total number of species in an ecosystem

Why is genetic diversity important for populations?

• It increases the number of species in an ecosystem

• It helps populations adapt to environmental changes

• It reduces the number of habitats needed

• It ensures all individuals are identical

What is a bottleneck event?

• A process that increases genetic diversity

• A type of genetic mutation

• An environmental disturbance that reduces population size

• A method of measuring species richness

What is a potential consequence of inbreeding in small populations?

• More balanced ecosystems

• Increased risk of harmful mutations

• Higher genetic diversity

• Increased species richness

How did scientists help the Florida panther population recover?

• By reducing the number of predators

• By increasing the number of habitats

• By increasing food supply

• By introducing pumas to increase genetic diversity

What is ecosystem resilience?

• The ability of an ecosystem to return to its original state after a disturbance

• The genetic diversity within a population

• The ability of an ecosystem to resist change

• The number of species in an ecosystem

How does high species diversity contribute to ecosystem resilience?

• By increasing the likelihood of quick recovery

• By ensuring all species are identical

• By decreasing genetic diversity

• By reducing the number of disturbances

What role do plants play in ecosystem recovery?

• They increase soil erosion

• They provide shelter and food for animals

• They reduce species diversity

• They decrease nutrient recycling
