Human Impacts on Biodiversity - AP Environmental Science

  1. How does climate change affect biodiversity?
    It alters habitats and causes species migration. Temperature changes force species to relocate.
  2. How does noise pollution affect wildlife?
    It disrupts communication and breeding behaviors. Loud sounds interfere with animal activities.
  3. Which treaty aims to protect biodiversity globally?
    The Convention on Biological Diversity (CBD). International agreement for conservation efforts.
  4. What is the role of conservation biology?
    To study and protect biodiversity. Scientific field focused on preserving species.
  5. Identify a benefit of maintaining biodiversity.
    Increases ecosystem resilience and productivity. More species provide stability and services.
  6. What is the impact of industrial agriculture on biodiversity?
    It leads to habitat loss and pollution. Large-scale farming destroys natural ecosystems.
  7. Name a key method for protecting endangered species.
    Establishing protected areas and wildlife reserves. Safe zones prevent habitat loss and hunting.
  8. How does acid rain affect biodiversity?
    It damages ecosystems and reduces species survival. Acidic precipitation harms plants and aquatic life.
  9. Which greenhouse gas is most associated with human activity?
    Carbon dioxide (CO2CO_2). Released primarily from fossil fuel combustion.
  10. How does land conversion for agriculture impact biodiversity?
    Results in habitat destruction and species loss. Natural ecosystems replaced with farmland.
  11. Which practice leads to the introduction of invasive species?
    Global trade and transportation. Ships and cargo accidentally transport species.
  12. Which option describes genetic diversity?
    Variation in genes within a species. Genetic variety within populations of same species.
  13. Which human activity is a major cause of deforestation?
    Logging for timber and land clearing for agriculture. Both remove trees and clear forested areas.
  14. What is an invasive species?
    Non-native species that cause harm to ecosystems. Outcompete native species and disrupt food webs.
  15. What is the result of monoculture farming on biodiversity?
    It reduces genetic and species diversity. Single crops eliminate habitat variety.
  16. What is a wildlife corridor?
    A passage that connects fragmented habitats. Links separated habitat areas for movement.
  17. Identify a consequence of global warming on species distribution.
    Shifts in the range of species' habitats. Temperature increases force range shifts.
  18. Which process leads to desertification?
    Overgrazing and unsustainable land use practices. Degradation turns fertile land into desert.
  19. What is biodiversity?
    The variety of life in the world or a particular habitat. Encompasses all living organisms and their genetic variations.
  20. What is the effect of overfishing on marine biodiversity?
    It reduces fish populations and disrupts ecosystems. Removes fish faster than they can reproduce.
  21. Identify a major effect of urbanization on biodiversity.
    Loss of habitat and increased pollution. Cities replace natural habitats with infrastructure.
  22. What is the significance of keystone species?
    They play a crucial role in ecosystem functioning. Their loss causes disproportionate ecosystem collapse.
  23. What is the role of an ecological footprint in biodiversity loss?
    Measures human demand on Earth's ecosystems. Quantifies resource consumption impact.
  24. Identify a human activity that leads to soil erosion.
    Deforestation and unsustainable agricultural practices. Both remove protective vegetation cover.
  25. What is the result of coral bleaching on marine ecosystems?
    Loss of biodiversity in coral reef habitats. Stressed corals expel algae, often dying.
  26. How does poaching affect biodiversity?
    It reduces populations of targeted species. Illegal hunting decreases endangered species numbers.
  27. Which conservation practice involves habitat restoration?
    Reforestation and wetland rehabilitation. Rebuilds damaged natural ecosystems.
  28. Identify a consequence of agricultural runoff.
    Eutrophication leading to dead zones in water bodies. Excess nutrients cause oxygen depletion.
  29. Identify a strategy to mitigate climate change effects on biodiversity.
    Creating wildlife corridors to facilitate migration. Connects habitats to enable species movement.
  30. How does pollution affect biodiversity?
    It contaminates habitats and affects species health. Toxic substances harm organisms and habitats.
  31. What is habitat fragmentation?
    The breaking of habitats into smaller, isolated patches. Isolates populations and reduces gene flow.
  32. What is the principle of sustainable development?
    Meeting present needs without compromising future generations. Balances current use with future availability.
  33. What is the impact of plastic pollution on marine life?
    Ingestion and entanglement harm marine organisms. Animals eat plastic or get trapped in debris.
  34. What is the primary source of ocean acidification?
    Increased CO2CO_2 absorption by the ocean. Dissolves in seawater, lowering ocean pH.
  35. Identify the primary cause of habitat destruction.
    Human activities such as agriculture and urbanization. Human development destroys natural ecosystems.
  36. How does tourism affect biodiversity?
    Can lead to habitat disturbance and pollution. Human activities can damage fragile ecosystems.
  37. How do pesticides impact biodiversity?
    They can harm non-target species and reduce diversity. Chemicals kill beneficial insects and soil organisms.
  38. What is the impact of oil spills on marine life?
    Oil spills harm marine organisms and habitats. Toxic substances coat organisms and destroy habitats.
