Environmental Systems and Societies Revision for test week Ecosystems – “An assemblage of parts working together forming a functioning whole.” “A community of independent organisms and the physical environment they inhabit.” All systems have many small parts working together. A system can be living (BIOTIC FACTORS) or non-living (ABIOTIC FACTORS) and has inputs as well as outputs. A system can be an abstract concept as well as something tangible. All systems have: * STORAGES * FLOWS

Example of a mutualistic relationship An example of a mutualistic relationship in the Daintree rainforest is the relationship between the Ulysses butterfly and the pink flowered doughwood. This relationship is mutualistic because the pink flowered doughwood needs a specific insect pollinator‚ the Ulysses butterfly‚ and the Ulysses butterfly relies on the pink flowered doughwood for the nectar on which it survives‚ making them both benefit and rely on each other. Example of a commensal relationship

latitude of the Amazon rainforest is longitude = 71 degrees‚ 45’ and 55”W and latitude = 15 degrees 31’ and 05”S. Biotic Components Animals -- boa constrictor -- toucan -- poison dart frog Plants -- ferns -- algae -- rattan palms Abiotic Components The Amazon Rainforest has a rainy and dry season. The annual rainfall is 2104mm and the temperature range is 73 F to 86 F. (abiotic factors - Amazon rainforest‚ n.d.) The poor quality of soil requires the plants to store their nutrients inside

is home to a magnificent rocky shore perfectly suited for a vast majority and wide range of marine wildlife. The rocky shore has a wide spread of both biotic and abiotic factors which provides a suitable ecosystem for all wildlife but unfortunately this unindustrialized location is becoming over developed. This takes a toll on Hastings point ecosystem immensely because the estuary‚ beach and the living organisms are slowly diminishing in numbers whilst the waters of the estuary are being polluted and
