Relationships in the Environment Diagram


  1. Available resources (e.g. food, water, shelter)
  2. Activities of other organisms (e.g. predators, disease-causing parasites)
  3. Organism's own characteristics (e.g. gestation period, number of young produced, nurturing of young, migratory)
  4. Time of day or year (e.g. tides, seasons, nocturnal or diurnal)
  5. Weather (e.g. amount of rainfall, cyclone, drought)


  1. Structural - related to the structure of the organism (e.g. The streamlined shape of fish enables it to swim more quickly through water.)
  2. Colour - related to colour (e.g. camouflage, warning colouration of blue-ringed octopus, mimicry of butterfly wings with 'eye spot')
  3. Physiological - related to the organism's metabolism (e.g. During hibernation, bears reduce their chemical processes.)
  4. Behavioural - related to behaviour (e.g. During the heat of the day in the desert, lizards burrow into the sand to find a cooler place.)
  5. Reproductive - related to courtship, mating or rearing of young (e.g. Peacocks fan their feathers to attract a mate.)
