    • What is an adaptation?
      A special feature for survival in a habitat
    • What is an extremophile?
      An organism adapted to extreme environments
    • Name a structural adaptation.
      Sharp teeth or thick fur
    • Name a functional adaptation.
      Producing venom to catch prey
    • Name a behavioral adaptation.
      Hibernating during winter
    • How is a polar bear adapted to its habitat?
      Thick fur and fat reduce thermal loss
    • How is a camel adapted to a desert environment?
      Stores fat in humps for water conversion
    • How is a cactus adapted to a dry environment?
      Thick stems store water effectively
    • What do the arrows in a food chain show?
      The flow of energy through an ecosystem
    • What is a producer?
      A green plant or algae that photosynthesize
    • Where does all the energy in a food chain originally come from?
      The sun
    • What is interdependence?
      Species numbers depend on each other
    • Why can't food chains support many trophic levels?
      Energy is lost at each trophic level
    • Define distribution.
      Where we find organisms
    • Define abundance.
      How many organisms we find
    • How do you work out the 'mode' from data?
      The one which occurs most often
    • How do you work out the 'median' from data?
      Arrange numbers and find the middle
    • How do you work out the 'mean' from data?
      Add all values and divide by total
    • How do you work out the 'range' from data?
      Take the largest value and subtract smallest
    • What is a quadrat?
      A square device for sampling techniques
    • What is the carbon cycle?
      Continuous passing of carbon between atmosphere and organisms
    • Name a process that removes carbon from the atmosphere.
      Photosynthesis by plants and algae
    • Name 2 processes that return carbon to the atmosphere.
      Respiration and decay
    • What is the process by which carbon is passed along food chains?
      Feeding passes carbon in the form of glucose
    • What organisms carry out decay?
      Micro-organisms like bacteria and fungi
    • What is the water cycle?
      Continuous evaporation, precipitation, and transport of water
    • Define precipitation.
      Rainfall or any form of water falling
    • How are clouds formed?
      Through condensation of water vapor as it cools
    • What is the process by which water is taken up by plants?
      Transpiration
