Our Planet of Life

What does the term "biodiversity" encompass, and why is it important for ecosystems?

• The number of individuals in a population

• The overall variety of life in a particular area

• The geographic distribution of species

• The genetic makeup of a single species

Differentiate between species diversity and genetic diversity. Provide examples to illustrate each concept.

• Species Diversity: The differences in DNA among individuals of a population or species. Example: Rainforest biodiversity.

• Genetic Diversity: The number or variety of species in a particular area. Example: Polar bear adaptations.

• Species Diversity: The number or variety of species in a particular area. Example: Desert biodiversity.

• Genetic Diversity: The overall variety of life in a particular area. Example: Coral reef species.

In what ways does biodiversity vary among taxonomic groups and geographic regions? Provide specific examples.

• Biodiversity is uniform across all taxonomic groups and regions.

• Taxonomic groups have no influence on biodiversity.

• Biodiversity varies significantly among different groups of organisms and geographic regions.

• Biodiversity is highest in polar regions and lowest in tropical rainforests.

Discuss the economic value of biodiversity by citing examples of services and products that ecosystems provide.

• Biodiversity has no economic value.

• Timber production is the only economic benefit of biodiversity.

• Biodiversity provides economically valuable services and products, such as timber, water purification, and pharmaceuticals.

• Economic benefits of biodiversity are limited to recreational activities.

True or False: Ecosystem diversity reflects the richness and abundance of life in an ecosystem.

Provide two examples of ecosystem services that are a result of biodiversity.

• Clean water and social media platforms.

• Timber production and video games.

• Food crops and medicines.

• Mobile apps and recreation areas.

Match the term with its correct definition: Biodiversity Species Diversity Ecosystem Diversity

• The overall variety of life in a particular area.

• Differences in DNA among individuals of a population or species.

• The number or variety of species in a particular area.

What is genetic diversity?

• The variety of ecosystems in a region

• The differences in DNA among individuals of a population or species

• The number of species in a particular area

• The interactions between different taxonomic groups

What is one potential consequence of a decrease in genetic diversity within a population?

• Increased adaptability

• Enhanced resilience

• Increased risk of extinction

• Improved reproductive success

In the context of biodiversity, what does the term "endemism" refer to?

• The spread of invasive species

• Species unique to a specific geographic area

• The loss of genetic diversity

• A decline in ecosystem services
