  • 1.1 Populations and ecosystems
    • enviroment
      • Both the abiotic and biotic factors of a given area/time.
    • abiotic
      • All the non-living components e.g. temperature and rainfall
    • biosphere
    • population
    • ecosystem
    • community
    • habitat
    • niche

        • All the non-living components e.g. temperature and rainfall
      • biosphere
      • population
      • ecosystem
      • community
      • niche
    • All living components e.g. organism, competition and predation
      • biotic
      • The life supporting layer of land, air and water; which surrounds the earth
        • A group of inter-breeding organisms of one species in a habitat.
          • All the interacting biotic and abiotic features in a specific area.
            • Self contained functional units
          • Self contained functional units
          • Two major processes to consider:
            • All the interacting biotic and abiotic features in a specific area.
              • 1. The flow of energy through the system
                • trophic levels
                • food chains
                  • food webs

                • 2. The cycling of elements within the system
                  • Carbon cycle

                • Carbon cycle
              • Nitrogen cycle
                • All populations of different organisms living and interacting in a particular place at the same time.
                  • Where a community of organisms live
                    • All populations of different organisms living and interacting in a particular place at the same time.
                    • There are many habitats in an ecosystem
                      • Where an organism lives an what it dos there including the biotic and abiotic components required so :
                        • Th organism can : survive, reproduce and maintain a viable population

                      This Mind map contains a lot of the key definitions needed for studying ecology so would be useful for any student needed to study this topic as part of their specification.there is good use of colour to separate the main ideas. The addition of some images would help make the Mind map more memorable. team this up with a set of flashcards for the definitions to make a complete set of resources.
