6.1.3 Biodiversity Loss

• What is biodiversity loss defined as?

  Decline in life variety
• Genetic biodiversity loss reduces a species' ability to adapt to change
• Loss of species diversity leads to the loss of unique ecological roles.
• Match the level of biodiversity with its impact of loss:

  Ecosystem ↔️ Degradation of ecological services

  Genetic ↔️ Reduced adaptability to change

  Species ↔️ Loss of unique ecological roles
• Order the key causes of biodiversity loss from most to least impactful:

  1️⃣ Habitat destruction and fragmentation

  2️⃣ Overexploitation of resources

  3️⃣ Climate change

  4️⃣ Pollution

  5️⃣ Invasive species
• Overfishing is an example of overexploitation of resources that contributes to biodiversity loss.
• Climate change disrupts species' adaptations and alters their ecosystems
• What is the impact of invasive species on native biodiversity?

  Loss of native species
• Match the cause of biodiversity loss with its description:

  Habitat destruction ↔️ Human activities like urbanization

  Overexploitation ↔️ Overfishing and overhunting

  Climate change ↔️ Global warming and altered ecosystems

  Pollution ↔️ Chemical pollutants and plastic waste

  Invasive species ↔️ Non-native species outcompeting native ones
• Climate change can disrupt species' survival by altering their ecosystems.
• Pollution, including plastic waste, harms species' health and their ecosystems
• How do invasive species contribute to biodiversity loss?

  Outcompete native species
• What are two human activities that cause habitat destruction and fragmentation?

  Deforestation and urbanization
• Overexploitation includes overfishing, overhunting, and overharvesting
• How does climate change affect ecosystems and species survival?

  Disrupts adaptations and survival
• Invasive species outcompete native species, leading to ecosystem disruption
• Match the cause of biodiversity loss with its impact:

  Habitat destruction ↔️ Loss of habitats and fragmentation

  Overexploitation ↔️ Depletion of species populations

  Climate change ↔️ Disrupts species' adaptations

  Pollution ↔️ Harms species health

  Invasive species ↔️ Loss of native species
• What three levels of biodiversity are encompassed by the term "biodiversity loss"?

  Genetic, species, and ecosystem
• Climate change alters ecosystems and disrupts species' adaptations.
• Order the steps in the process of how biodiversity loss leads to ecosystem disruption:

  1️⃣ Loss of species

  2️⃣ Disruption of ecosystem balance

  3️⃣ Reduced ecosystem resilience
• What are three examples of ecosystem services affected by biodiversity loss?

  Pollination, water purification, nutrient cycling
• The loss of genetic resources and species due to biodiversity loss impacts food security and medicine
• The consequences of biodiversity loss are far-reaching and interconnected
• The loss of species reduces ecosystem resilience.
• Match the consequence of biodiversity loss with its description:

  Ecosystem disruption ↔️ Loss of species and ecosystem balance

  Loss of ecosystem services ↔️ Decline in pollination and water purification

  Decreased resource availability ↔️ Loss of genetic resources and species
• The loss of pollinator species like bees can significantly impact crop yields
• The loss of ecosystem services can negatively impact human well-being.
• Match the consequence of biodiversity loss with its impact:

  Ecosystem disruption ↔️ Reduced ecosystem resilience

  Loss of ecosystem services ↔️ Negative impacts on human well-being

  Decreased resource availability ↔️ Impacts on food security and medicine
• In the French Alps, habitat loss due to ski resort expansion affects the Alpine ibex
• Match the region with the affected ecosystem in French-speaking regions:

  French Alps ↔️ Mountain ecosystems

  Cameroon ↔️ Tropical rainforest

  New Caledonia ↔️ Coral reefs
• Biodiversity loss includes the decline in genetic variation within species.
• The loss of genetic biodiversity reduces a species' adaptability to change
• Match the level of biodiversity with its description:

  Genetic ↔️ Variation of genes within a species

  Species ↔️ Variety of different species

  Ecosystem ↔️ Range of habitats and ecological communities
• Habitat destruction leads to ecosystem fragmentation
• Pollution from chemicals and plastic waste harms species and ecosystems.
• The decline of bees in France disrupts pollination and affects agricultural production.
• Habitat conservation involves protecting and restoring ecosystems
• Match the strategy to mitigate biodiversity loss with an example:

  Habitat conservation ↔️ Establishing national parks

  Sustainable resource management ↔️ Adopting sustainable forestry practices

  Pollution reduction ↔️ Implementing regulations on industrial waste

  Invasive species control ↔️ Eradication programs for invasive plants
