Cards (26)

  • The five kingdoms
    • Animal
    • Plant
    • Fungi
    • Single-celled organisms
    • Bacteria
  • Vertebrates
    Animals with a backbone, including mammals, amphibians, reptiles, bony fish and birds
  • Invertebrates
    Animals without a backbone, including molluscs, annelids, arthropods and nematodes
  • The Plant Kingdom
    • Flowering
    • Non-flowering
  • Flowering plants
    Produce flowers for reproduction, e.g. grass plants and sunflowers
  • Non-flowering plants
    Do not produce flowers, reproduce using spores, e.g. ferns and mosses
  • Naming species
    • Kingdom
    • Phylum
    • Class
    • Order
    • Family
    • Genus
    • Species
  • Binomial system
    Uses the organism's genus and species to create its name, avoids confusion from common names, uses Latin
  • Morphological adaptation
    Structural change which gives an organism a greater chance of survival in its habitat
  • Behavioural adaptation
    The way an organism reacts to its environment which aids its survival
  • Things organisms compete for
    • Food
    • Territory
    • Mates
  • Things plants compete for
    • Light
    • Water
    • Minerals
  • Interspecific competition

    Competition between different species
  • Intraspecific competition

    Competition between members of the same species
  • Other factors that change population size
    • Predation
    • Pollution
    • Disease
  • Biodiversity
    A measure of the variety of different species and the numbers of each of those species in a particular area
  • Biodiversity is important for humans as a source of food, industrial materials and the potential for new medicines
  • Ways to conserve and protect biodiversity and endangered species
    • Convention on International Trade in Endangered Species (CITES)
    • Sites of Special Scientific Interest (SSSI)
    • Captive breeding programmes
    • National parks
    • Seed/sperm banks
    • Local biodiversity action plans
  • Quadrat
    Used to measure biodiversity
  • Assumptions made when using capture-recapture data include no death, immigration or emigration, and that the marking technique does not affect chances of survival
  • Predator
    An animal that hunts and eats another species for food
  • Prey
    An animal that is eaten by a predator
  • Pest
    An organism that eats a crop plant
  • Native species
    An organism that lives in the country
  • Alien Species
    An organism introduced into a country in which it does not normally live.
  • Invasive Species
    An alien organism that has had a negative effect on the native species.
