9.1.2 Biodiversity

• Biodiversity enhances ecosystem stability and resilience.


  True
• Ecosystem diversity refers to the variety of different ecosystems or habitats
• Biodiversity refers to the variety of life within a specific area
• Match the level of biodiversity with its example:

  Genetic Diversity ↔️ Different breeds of dogs

  Species Diversity ↔️ A rainforest's abundant species

  Ecosystem Diversity ↔️ Forests, wetlands, grasslands
• Order the factors affecting biodiversity from most destructive to least:

  1️⃣ Habitat destruction and fragmentation

  2️⃣ Pollution and climate change

  3️⃣ Invasive species

  4️⃣ Overexploitation

  5️⃣ Conservation efforts
• Conservation efforts aim to protect habitats and reintroduce endangered species
• Genetic diversity is illustrated by different breeds of dogs.


  True
• Ecosystem diversity includes forests, wetlands, and grasslands.

  True
• Habitat destruction reduces biodiversity by fragmenting ecosystems.


  True
• Conservation efforts can increase biodiversity by reintroducing endangered species.


  True
• Overexploitation of resources can lead to a decline in biodiversity.


  True
• Reintroducing endangered species is a method of protecting biodiversity.

  True
• Invasive species can outcompete and displace native species
• What are the three main levels of biodiversity?

  Genetic, species, ecosystem
• What does species diversity measure?

  Number of species
• Why is biodiversity important for ecosystem stability?

  Enhances resilience
• How does pollution affect biodiversity?

  Disrupts ecosystem balance
• What are the effects of habitat fragmentation on biodiversity?

  Decreases biodiversity
• What is one method of protecting biodiversity through habitat preservation?

  Restoring natural areas
• How does invasive species control help maintain biodiversity?

  Removes non-native species
• Biodiversity provides valuable resources such as food and medicines
• Higher biodiversity allows ecosystems to better withstand disturbances.


  True
• Habitat destruction can reduce biodiversity.


  True
• Genetic diversity refers to the variation within a species
• Ecosystem diversity refers to the variety of different ecosystems
• Higher levels of biodiversity allow ecosystems to better withstand disturbances and adapt to changes
• Invasive species reduce biodiversity by outcompeting native species
• Climate change can disrupt ecosystems and cause species to become extinct
• Sustainable resource management ensures resources are used responsibly to protect biodiversity
