Cards (17)

  • How does farming affect biodiversity?
    Farming reduces biodiversity
  • What role do hedgerows play in biodiversity?
    They provide a habitat for insects and birds
  • What is the impact of selecting breeding on biodiversity?
    Narrowing the gene pool reduces diversity
  • What is monoculture in farming?
    Growing an entire field with one crop
  • What is the effect of overgrazing on plants?
    It knocks out the plants
  • Why is farming important for humans?
    It provides food, especially with population growth
  • What is a compromise that can be made regarding hedgerows in farming?
    Remove two but not all hedgerows
  • What is selective breeding?
    Selecting plants/animals with desirable traits
  • What is crop rotation?
    Rotating crops each year in a field
  • How can biodiversity be described?
    As a range of habitats from local to global
  • Why might low biodiversity not be a concern in certain environments?
    Harsh abiotic factors limit organism survival
  • What is a common cause for a decrease in biodiversity?
    Human activities often cause decreases
  • What are the effects of farming practices on biodiversity?
    • Reduces biodiversity
    • Destroys hedgerows, habitats for species
    • Selective breeding narrows gene pool
    • Monoculture limits crop diversity
    • Overgrazing eliminates plant life
    • Filling in ponds and draining wetlands harms ecosystems
  • What are the key concepts related to biodiversity?
    • Range of habitats from local to global
    • Low biodiversity may be acceptable in harsh environments
    • Decrease in biodiversity is concerning
    • Often caused by human activities
  • What is the definition of species diversity?
    The number of species and individuals within each species in a community
  • What is the defintion of species richness?
    The number of different species in a particular area at the particular time.
  • What is an acronym for farming reducing biodiversity?
    1.H- hedgerows
