36. POPULATIONS AND COMMUNITIES, EXPERIMENTAL MODELLING - Coggle Diagram

- - - - BOTH SPECIES BENEFIT FROM THE INTERACTION
      - ROOT NODULES IN FABACEAE
        
        LEGUMES GAIN NITRATES AND BACTERIA GAINS CARBOHYDRATES
      - MICORRHIZAE IN ORCHIDACEAE
        
        THE FUNGUS FORMS AN ASSOCIATION WITH THE PLANT, CALLED MICORRHIZAE
        
        THE HYPHAE INCREASES THE SURFACE AREA OF THE ROOT SYSTEM WHILE THE FUNGUS GAINS CARBOHYDRATES FROM THE PLANT
      - ZOOXANTHELLAE IN CORAL POLYPS
        
        ZOOXANTHELLAE PROVIDES CARBOHYDRATES TO THE POLYP AND THE POLYP SECRETES CALCIUM CARBONATE EXOSKELETON
    - - ONE SPECIES BENEFITS, THE OTHER IS UNAFFECTED
      - BARNACLES ARE TRANSPORTED TO PLANKTON-RICH WATERS BY ATTACHING TO WHALES
    - - ONE SPECIES BENEFITS TO THE DETRIMENT OF THE OTHER
      - TICKS FEED ON THE BLOOD OF THEIR CANINE HOST
- - - - M - NUMBER OF INDIVIDUALS CAUGHT AND MARKED INITALLY
      - N - NUMBER OF RECAPTURED INDIVIDUALS
      - R - NUMBER OF RECAPTURED INDIVIDUALS WITH MARKS
      - M X (N/R)
    - - NO MIGRATION INTO OR OUT OF THE POPULATION
      - NO DEATHS OR BIRTHS
      - THE MARKS REMAIN VISIBLE
      - MARKED INDIVIDUALS REINTEGRATE IN THE POPULATION AND HAVE THE SAME CHANCE OF BEING CAPTURED FROM PREDATORS
