    • Climate change threatens food and water security
    • What are ecosystems composed of?
      Living organisms and physical environment
    • Match the climate change impact with its description:
      Shifts in species distribution ↔️ Species migrate poleward or altitudinally
      Changes in ecosystem structure ↔️ Loss of keystone species affects food webs
      Increased risk of extinction ↔️ Habitat loss and inability to adapt
      Disruption of ecosystem services ↔️ Reduced provision of clean air and water
    • Habitat fragmentation due to climate change makes it difficult for species to adapt and survive.

      True
    • Decreased rainfall in deserts threatens the survival of desert-adapted species
    • Climate change refers to the long-term shift in global or regional climate patterns.

      True
    • Arrange the following components of an ecosystem from smallest to largest:
      1️⃣ Living organisms
      2️⃣ Physical environment
      3️⃣ Ecosystem
    • Biodiversity is crucial for maintaining the health and resilience of natural environments.

      True
    • Decreased rainfall in deserts leads to scarcity of water sources
    • How does climate change affect crops according to the study material?
      Reduced yields
    • Heat stress reduces livestock productivity.
      True
    • What is the primary driver of climate change according to the study material?
      Human-induced greenhouse gas emissions
    • Climate change poses a serious threat to human well-being and requires coordinated global efforts.

      True
    • Order the key impacts of climate change on ecosystems:
      1️⃣ Shifts in species distribution and abundance
      2️⃣ Changes in ecosystem structure and function
      3️⃣ Increased risk of species extinction
      4️⃣ Disruption of ecosystem services
    • Ecosystems are more profoundly affected by climate change than human societies.

      True
    • What is biodiversity crucial for?
      Maintaining ecosystem health and resilience

      Rapid pace of environmental change
    • Understanding disruptions to terrestrial ecosystems is crucial for developing effective conservation strategies.

      True
    • Match the impact of climate change with its description:
      Shifts in species distribution ↔️ Species migrate in response to warming temperatures
      Changes in ecosystem structure ↔️ Disruption of food webs and keystone species
      Increased risk of extinction ↔️ Habitat loss and inability to adapt
    • What happens to cold-adapted species due to warming temperatures?
      They decline
    • Match the impact of climate change on biodiversity with its consequence:
      Habitat loss and fragmentation ↔️ Makes adaptation difficult for species
      Increased extinction risk ↔️ Outpaces species' ability to adapt
      Changes in ecosystem structure ↔️ Disrupts nutrient cycling and food webs
    • Arrange the following impacts of climate change on marine ecosystems from most direct to indirect:
      1️⃣ Ocean acidification
      2️⃣ Sea level rise
      3️⃣ Changes in ocean currents
      4️⃣ Warming temperatures
    • What is food security defined as?
      Access to safe food
    • What is the main impact of ocean acidification on fisheries?
      Declines in fish stocks
    • What primarily drives climate change?
      Greenhouse gas emissions
    • Climate change disrupts ecosystem services, such as the provision of clean air and water
    • The cascading effects of biodiversity loss can compromise ecosystem resilience.
      True
    • Rising sea levels can lead to habitat fragmentation.

      True
    • Climate change reduces carbon sequestration in forests.

      True
    • Arrange the effects of climate change on marine ecosystems in a logical order:
      1️⃣ Disruption of ocean currents
      2️⃣ Changes in nutrient distribution
      3️⃣ Impact on marine food webs
    • Match the water resource impact with its description:
      Saltwater intrusion ↔️ Contamination of coastal aquifers
      Flooding ↔️ Damage from extreme weather
      Water scarcity ↔️ Reduced precipitation patterns
    • What is one mental health impact of climate-related disasters?
      Increased stress
    • Climate-induced migration and competition for resources can lead to social unrest and conflict.

      True
    • Reduced crop yields due to changes in precipitation patterns are an economic impact of climate change on agriculture.

      True
    • Climate-related migration can exacerbate existing tensions and lead to violent conflicts over resources.

      True
    • Climate change can disrupt food webs and ecosystem services.

      True
    • Ecosystems are highly sensitive to changes in climate because they rely on delicate balances between various components.

      True
    • Biodiversity refers to the variety of living species and the ecosystems they inhabit.
    • What does biodiversity loss compromise in ecosystems?
      Resilience and stability
    • Match the terrestrial ecosystem with the impact of climate change:
