7.3.1 Biodiversity

• Genetic biodiversity enhances adaptability and survival in changing environments
• What does ecosystem biodiversity support?

  Diverse ecological roles
• Species biodiversity refers to the number and types of species in a habitat


  True
• Genetic biodiversity enhances adaptability and survival in changing environments
• Why is species biodiversity crucial for ecosystem functioning?

  Maintains stability
• Genetic biodiversity ensures survival in changing environments

  True
• Wetlands filter pollutants, providing clean water
• How does biodiversity contribute to economic stability?

  Underpins tourism
• Why is species biodiversity crucial for ecosystem stability?

  Maintains ecosystem functioning
• Order the levels of biodiversity from smallest to largest scale:

  1️⃣ Genetic

  2️⃣ Species

  3️⃣ Ecosystem
• An ecosystem supports diverse ecological roles and processes
• What is the importance of genetic diversity within a species?

  Enhances adaptability and survival
• The three levels of biodiversity are equally important for maintaining resilient ecosystems.


  True
• Match the benefit of biodiversity with its description:

  Ecosystem Stability ↔️ Enhances resilience to disturbances

  Ecosystem Functioning ↔️ Supports vital ecological processes

  Human Well-being ↔️ Provides food, medicine, recreation

  Economic Stability ↔️ Underpins tourism, agriculture, fisheries
• What does biodiversity refer to?

  Variety of life
• Species biodiversity is crucial for ecosystem stability


  True
• Genetic biodiversity arises from differences in genes
• What is the importance of ecosystem biodiversity?

  Supports ecological processes
• Match the level of biodiversity with its description:

  Genetic ↔️ Differences in genes within a single species

  Species ↔️ Number and types of species in a habitat

  Ecosystem ↔️ Range of ecosystems and their habitats
• Ecosystem biodiversity supports diverse ecological roles and processes
• What is the role of biodiversity in ecosystem stability?

  Enhances resilience
• Match the benefit of biodiversity with its description:

  Ecosystem Stability ↔️ Resilience to environmental changes

  Ecosystem Functioning ↔️ Supports vital ecological processes

  Human Well-being ↔️ Provides food, medicines, and recreation
• Genetic diversity is enhanced by differences in genes within a single species

  True
• Ecosystem biodiversity includes tropical rainforests, deserts, and tundra
• What two factors are crucial for ecosystem functioning and stability?

  Ecosystem functioning and stability
• Arrange the three levels of biodiversity in order of scale, from smallest to largest.

  1️⃣ Genetic

  2️⃣ Species

  3️⃣ Ecosystem
• The number and types of species living in a habitat contribute to species biodiversity.
• In what three areas does biodiversity play a crucial role?

  Healthy ecosystems, human well-being, economic stability
• Wetlands filter pollutants, providing clean water for communities.
• What is the primary impact of habitat loss on biodiversity?

  Reduction in space and resources
• Arrange the following threats to biodiversity in order from most immediate to most long-term impact:

  1️⃣ Pollution

  2️⃣ Overexploitation

  3️⃣ Habitat Loss

  4️⃣ Climate Change
• What is the main purpose of designating protected areas as a conservation strategy?

  Preserves habitats and allows species to thrive undisturbed
• Species conservation efforts aim to maintain genetic diversity and prevent extinction.


  True
• What is the role of education and awareness in biodiversity conservation?

  Informing the public about biodiversity
• Coral reefs attract tourists, benefiting local economies.


  True
• Deforestation for farming is an example of habitat loss.
• Match the threat to biodiversity with its example:

  Habitat Loss ↔️ Deforestation for farming

  Pollution ↔️ Industrial waste in rivers

  Overexploitation ↔️ Overfishing leading to collapse of fish stocks

  Climate Change ↔️ Rising sea levels affecting coastal ecosystems

  Invasive Species ↔️ Cane toads in Australia outcompeting native frogs
• Habitat restoration aims to rebuild essential ecological functions.
• Match the conservation strategy with its importance:

  Protected Areas ↔️ Preserves habitats and allows species to thrive undisturbed

  Habitat Restoration ↔️ Rebuilds essential ecological functions

  Species Conservation ↔️ Prevents extinction and maintains genetic diversity

  Sustainable Resource Use ↔️ Balances human needs with environmental protection
• Conservation efforts ensure the long-term sustainability of ecosystems.
