What is biodiversity and why is it important?

• Biodiversity is the variety of life on Earth, and it is important for ecosystem stability, resource provision, and essential ecosystem services.

• Biodiversity is only important for human health and not for ecosystems.

• Biodiversity is the total biomass of all organisms on Earth.

• Biodiversity refers to the number of species in a single habitat.

Name three major threats to biodiversity.

• Habitat loss, climate change, pollution

• Natural disasters, overfishing, urbanization

• Agricultural expansion, resource depletion, genetic modification

• Overpopulation, deforestation, invasive species

How does habitat destruction impact biodiversity?

• Habitat destruction has no effect on biodiversity.

• Habitat destruction increases biodiversity by creating new species.

• Habitat destruction significantly reduces biodiversity by eliminating species and disrupting ecosystems.

• Habitat destruction only affects plant species, not animals.

What role do protected areas play in biodiversity preservation?

• Protected areas have no impact on species survival.

• Protected areas play a vital role in preserving biodiversity by providing safe habitats for species and maintaining ecosystem health.

• Protected areas are primarily used for recreational activities.

• Protected areas are only beneficial for tourism development.

Explain the concept of an ecological footprint.

• The ecological footprint quantifies the demand on Earth's ecosystems and compares it to the planet's ability to regenerate resources.

• The ecological footprint refers to the total area of land occupied by a single species.

• The ecological footprint is a method to calculate the average temperature of the Earth.

• The ecological footprint measures the number of species in an ecosystem.

What are invasive species and how do they affect native biodiversity?

• Invasive species are always beneficial to ecosystems.

• Invasive species are native organisms that enhance biodiversity.

• Invasive species are non-native organisms that negatively impact native biodiversity by outcompeting native species, introducing diseases, and altering habitats.

• Invasive species do not affect the food chain or habitat structure.

Describe the significance of genetic diversity in ecosystems.

• Genetic diversity enhances ecosystem resilience, adaptability, and stability.

• Genetic diversity has no impact on ecosystem health.

• Genetic diversity reduces the number of species in an ecosystem.

• Genetic diversity leads to increased competition among species.

How can sustainable practices help conserve biodiversity?

• Sustainable practices have no impact on wildlife populations.

• Sustainable practices increase pollution and habitat destruction.

• Sustainable practices promote overfishing and deforestation.

• Sustainable practices conserve biodiversity by protecting ecosystems and reducing environmental impact.

What is the relationship between biodiversity and ecosystem services?

• Biodiversity and ecosystem services are unrelated concepts.

• Biodiversity decreases ecosystem services by reducing species variety.

• Biodiversity enhances ecosystem services by increasing resilience and productivity.

• Ecosystem services have no impact on biodiversity levels.

Discuss the impact of climate change on biodiversity.

• Biodiversity thrives in changing climates.

• Climate change has no effect on biodiversity.

• Climate change only affects human populations, not biodiversity.

• Climate change negatively impacts biodiversity by causing habitat loss, altering ecosystems, and increasing extinction rates.
