Show Answers:

  1. Biodiversity
    The amount of different species in an area
  2. Protect
    Stopping further/any harm to a biotic and/or abiotic "thing"
  3. Biodiversity Hotspot
    • An area where there is a large amount of biodiversity
    • usually tropical areas
  4. Community
    a group of organisms living in the same place or having a particular characteristic in common.
  5. Dominant Species
    • A species that greatly influences the ecosystem it is in
    • generally primary producers
  6. Keystone Species
    • A species that is needed for the ecosystem to thrive
    • An undercommon species
  7. Captive breeding
    • Keeping a certain species in a contained way and having it breed to increase its population
    • done only with endangered species
    • The Toronto zoo commonly does this
  8. Ecosystem engineer
    • A species that greatly influences the environment of a given ecosystem
    • i.e. a beaver and it's dam
  9. Succession
    a number of species or things sharing a specified characteristic and following one after the other.
  10. Habitat loss
    • The loss of a species habitat

    Planting trees to recreate a forest which was previously destroyed
  19. Biocontrol
    • Using a species to control the population of another
    • i.e. using cats to kill mice
  20. Bioremediation
    Using plants to put nutrients back into destroyed soil
  21. Bioaugmentation
    Using plants to remove harmful chemicals/materials from soil
