8.7 Disruptions to Ecosystems

• What is a disruption in an ecosystem?

  Disturbance or change
• Match the type of disruption with its description:

  Natural Disasters ↔️ Events like hurricanes or floods that destroy habitats

  Human Activities ↔️ Pollution or urbanization that degrades ecosystems

  Invasive Species ↔️ Non-native species outcompeting native species
• What are the two main types of disruptions that can impact ecosystems?

  Natural and human-induced
• What are examples of human activities that cause ecosystem disruptions?

  Pollution, deforestation
• What are the ecological effects of deforestation on ecosystems?

  Habitat loss, reduced biodiversity
• What are three major human-induced disruptions to ecosystems?

  Deforestation, pollution, climate change
• What does pollution degrade in ecosystems?

  Air, water, and soil
• A disruption in an ecosystem refers to a disturbance or change that alters its normal functioning and balance
• Order the potential effects of ecosystem disruptions:

  1️⃣ Changes in species composition

  2️⃣ Changes in population sizes

  3️⃣ Alterations in nutrient cycling
• Human activities such as pollution reduce biodiversity and degrade environmental quality
• Match the natural disruption with its ecological effect:

  Volcanic Eruptions ↔️ Destroys habitats and air quality

  Earthquakes ↔️ Physically damages ecosystems

  Wildfires ↔️ Burns vegetation and affects wildlife
• What do earthquakes primarily damage in ecosystems?

  Earth's crust and landscapes
• Human-induced disruptions can lead to changes in critical ecological processes.


  True
• A disruption in an ecosystem refers to a disturbance or change that alters its normal functioning and balance
• Disruptions in ecosystems can lead to changes in species composition and nutrient cycling.


  True
• Natural disasters such as hurricanes can disrupt ecosystems by physically damaging or destroying habitats
• Order the ecological effects of different natural disruptions:

  1️⃣ Volcanic eruptions destroy habitats

  2️⃣ Earthquakes damage ecosystems

  3️⃣ Wildfires burn vegetation
• Climate change can disrupt ecosystems by altering temperature and precipitation patterns.


  True
• Deforestation reduces biodiversity and disrupts water regulation
• Climate change can cause habitat loss and species migration.

  True
• Match the type of disruption with its description:

  Natural Disasters ↔️ Events like hurricanes or wildfires

  Human Activities ↔️ Pollution or deforestation

  Invasive Species ↔️ Non-native species outcompeting native ones

  Climate Change ↔️ Long-term shifts in environmental conditions
• What are two main types of disruptions that can impact ecosystems?

  Natural and human-induced
• Natural disasters can destroy habitats and disrupt ecological processes.


  True
• Name three natural disasters that can cause ecosystem disruptions.

  Volcanic eruptions, earthquakes, wildfires
• Volcanic eruptions release ash and lava, disrupting air and water quality.


  True
• Wildfires burn through forests and grasslands, affecting wildlife habitats
• What are two key effects of ecosystem disruptions on populations and communities?

  Stress and altered balance
• Order the potential effects of disruptions on populations and communities:

  1️⃣ Migration of species

  2️⃣ Population declines

  3️⃣ Degradation of the environment
• A natural disaster like a hurricane can destroy habitats
• Reduced biodiversity refers to a decline in the variety of species
• Habitat loss involves the destruction of physical environments species depend on.


  True
• What does ecosystem resilience refer to?

  Withstanding disruption impacts
• Match the concept with its definition:

  Ecosystem Resilience ↔️ The ability to withstand and absorb the impacts of a disruption

  Ecosystem Recovery ↔️ The process of returning to the original state after a disruption
• Habitat protection preserves biodiversity and supports ecological balance.


  True
• Match the sustainable practice with its impact:

  Sustainable Fishing ↔️ Reduces overfishing and protects marine ecosystems

  Sustainable Farming ↔️ Minimizes soil degradation and pollution
• Human activities like pollution reduce available resources
• Ecosystem disruptions can stress or alter the balance
• Human activities like pollution can poison organisms and reduce resources.

  True
• Disrupted food webs can alter the flow of energy and nutrients
• What is the process of ecosystem recovery after a disruption?

  Returning to original state
