4.5 Biodiversity

• What does biodiversity refer to in a given area?

  Variety of living organisms
• Genetic diversity refers to the variety of genetic information within a species.


  True
• Genetic biodiversity refers to the variety of genetic information within a species
• Habitat destruction reduces the available space and resources for species
• Invasive species outcompete native species for resources, reducing biodiversity.


  True
• Species biodiversity supports the resilience of ecosystems, allowing them to better adapt to changes
• Genetic biodiversity enables species to resist diseases more effectively.

  True
• What ecosystem service does ecosystem biodiversity ensure?

  Water purification
• Match the level of biodiversity with its definition:

  Species diversity ↔️ The number and variety of different species in an area

  Genetic diversity ↔️ The variety of genetic information within a species

  Ecosystem diversity ↔️ The variety of different ecosystems
• What type of biodiversity is exemplified by a rainforest ecosystem with diverse plants and animals?

  Species biodiversity
• What is the primary impact of habitat destruction on biodiversity?

  Reduces species diversity
• How do invasive species affect biodiversity?

  Outcompete native species
• Order the levels of biodiversity from highest to lowest impact on ecosystem stability.

  1️⃣ Ecosystem biodiversity

  2️⃣ Species biodiversity

  3️⃣ Genetic biodiversity
• Species diversity is the number and variety of different species in an area
• What is an example of ecosystem diversity?

  Variety of ecosystems
• Species biodiversity is illustrated by a rainforest ecosystem with diverse plants and animals.


  True
• What is an example of ecosystem biodiversity?

  Variation between ecosystems
• Order the factors affecting biodiversity from most to least direct impact:

  1️⃣ Habitat destruction

  2️⃣ Pollution

  3️⃣ Climate change

  4️⃣ Invasive species

  5️⃣ Overexploitation
• Why is ecosystem biodiversity important?

  Maintains ecosystem stability
• What does species biodiversity contribute to ecosystems?

  Resilience
• Ecosystem biodiversity maintains the stability and functioning of ecosystems
• Define biodiversity in a single sentence.

  Variety of living organisms
• Provide an example of genetic biodiversity.

  Different breeds of dogs
• The variation between desert, grassland, and forest ecosystems is an example of ecosystem biodiversity.
• Climate change can force species to adapt or migrate.


  True
• What is the potential outcome of overexploitation of a species?

  Extinction
• Match the conservation strategy with its impact on biodiversity:

  Protected areas ↔️ Maintains ecosystem stability

  Habitat restoration ↔️ Rebuilds ecosystems

  Species reintroduction ↔️ Restores ecological balance
• What does species reintroduction aim to achieve?

  Rebuild endangered populations
• Protected areas help preserve habitats and maintain ecosystem stability.
• Implementing multiple conservation strategies is essential for maintaining biodiversity.
