Ecosystem Services - Middle School Life Science

  1. Identify the ecosystem service provided when forests store carbon and help moderate climate.
    Climate regulation (regulating service). Trees absorb CO₂ and release oxygen, stabilizing climate.
  2. Identify the ecosystem service provided when plant roots hold soil in place and reduce erosion.
    Erosion control (regulating service). Roots stabilize soil, preventing loss of fertile topsoil.
  3. Which ecosystem service category includes products like food, timber, and fresh water?
    Provisioning services. These are tangible products directly obtained from nature.
  4. Identify the ecosystem service provided when a forest provides wood used for building materials.
    Timber/wood supply (provisioning service). Forests provide a harvestable product for human use.
  5. What is water purification by wetlands most directly classified as?
    Regulating service. Wetlands regulate water quality by filtering pollutants.
  6. What is erosion control by plant roots most directly classified as?
    Regulating service. Plants regulate soil stability and prevent land degradation.
  7. What is an ecosystem service?
    A benefit people obtain from ecosystems that supports human well-being. These services are essential for human survival and quality of life.
  8. What term describes the variety of life in an area that helps ecosystems stay stable and resilient?
    Biodiversity. Variety of species ensures ecosystem health and function.
  9. Identify the ecosystem service: Bees pollinate crops, increasing fruit production.
    Regulating service (pollination). Bees regulate crop reproduction through pollen transfer.
  10. What term describes benefits people obtain from ecosystems, such as clean water and pollination?
    Ecosystem services. These benefits support human well-being and survival.
  11. Which ecosystem service category includes flood control and climate regulation?
    Regulating services. These services help maintain environmental balance and stability.
  12. Which ecosystem service category includes nutrient cycling and soil formation?
    Supporting services. These are essential processes that enable all other services.
  13. Identify the ecosystem service: A wetland filters runoff, improving downstream water quality.
    Regulating service (water purification). Wetlands regulate water quality through natural filtration.
  14. What is decomposition of dead organisms most directly classified as?
    Supporting service. Decomposition supports nutrient availability for all life.
  15. Identify the ecosystem service: A forest trail provides recreation and mental health benefits.
    Cultural service (recreation). Natural areas provide non-material benefits for well-being.
  16. Identify the ecosystem service provided when a natural area is used for hiking and outdoor recreation.
    Recreation (cultural service). Nature provides non-material enjoyment and well-being.
  17. Identify the ecosystem service provided when wetlands reduce flooding by storing stormwater.
    Flood regulation (regulating service). Wetlands act as natural sponges, absorbing excess water.
  18. Identify the ecosystem service provided when ecosystems naturally filter pollutants from water.
    Water purification (regulating service). Natural filtration removes harmful substances from water.
  19. Identify the ecosystem service provided when a river supplies drinking water for a town.
    Freshwater supply (provisioning service). Rivers provide a tangible resource people can collect.
  20. Which type of ecosystem service is most directly harmed when habitat loss reduces biodiversity?
    Supporting services. Biodiversity loss disrupts basic ecosystem processes.
  21. Identify the ecosystem service provided when algae and plants produce organic matter that supports food webs.
    Primary production (supporting service). This forms the base of all food chains and ecosystems.
  22. Identify the ecosystem service provided when decomposers break down dead matter and return nutrients to soil.
    Nutrient cycling (supporting service). This recycling maintains soil fertility for plant growth.
  23. Identify the ecosystem service: Decomposers recycle nutrients that support plant growth.
    Supporting service (nutrient cycling). Decomposers support ecosystem productivity through recycling.
  24. What is soil formation over time most directly classified as?
    Supporting service. Soil formation supports all terrestrial ecosystem functions.
  25. Identify the ecosystem service provided when people fish in a lake for food.
    Food provision (provisioning service). Lakes provide harvestable fish as a tangible resource.
  26. What is medicinal compound production by plants most directly classified as?
    Provisioning service. Plants provide compounds used in medicines and treatments.
  27. Identify the ecosystem service: Mangroves reduce storm surge and protect coastal homes.
    Regulating service (coastal protection). Mangroves regulate wave energy and protect shorelines.
  28. Which ecosystem service category includes recreation, aesthetic value, and spiritual benefits?
    Cultural services. These are non-material benefits that enrich human life.
  29. What is seafood harvested from oceans most directly classified as?
    Provisioning service. Oceans provide food products directly to humans.
  30. Identify the ecosystem service provided when bees move pollen between flowers to form seeds and fruit.
    Pollination (regulating service). Bees regulate plant reproduction, enabling food production.
  31. Which ecosystem service is most directly reduced when wetlands are drained and downstream flooding increases?
    Flood regulation (regulating service). Lost wetlands can't absorb excess stormwater.
  32. Which ecosystem service category includes nutrient cycling, soil formation, and primary production?
    Supporting services. These are essential processes that enable all other services.
  33. What is carbon storage by forests most directly classified as?
    Regulating service. Forests regulate climate by storing atmospheric carbon.
  34. Which ecosystem service category includes food, fresh water, and timber?
    Provisioning services. These are products directly obtained from ecosystems.
  35. Which ecosystem service category includes recreation, tourism, and aesthetic value?
    Cultural services. These are non-material benefits that enrich human experiences.
  36. Which ecosystem service is most directly reduced when insect populations decline and crops set fewer fruits?
    Pollination (regulating service). Fewer pollinators means reduced crop yields.
  37. What are the four main categories of ecosystem services?
    Provisioning, regulating, supporting, and cultural services. This framework helps classify all ecosystem benefits to humans.
  38. What is nitrogen fixation by bacteria most directly classified as?
    Supporting service. This process supports plant growth by making nitrogen available.
  39. Which ecosystem service category includes climate regulation, flood control, and water purification?
    Regulating services. These services maintain environmental conditions we depend on.
