 Food Webs and Chains in Ecosystems around Maribyrnong – Newells Paddock Click the following to view images of the animals in the ecosystem: a)  Food chains: Acacia Acinacea --> Caterpillars --> Frogs --> Brown Snake --> Larger Snakes --> Specific Birds Acacia Acinacea --> Caterpillars/Beetles --> Skink --> Red Fox   b)   Food web: c) Both the acacia acinacea and the brachycome multifida are producers.  d)

f)  The organisms that are predators are the Little Pied Comorant, Red Foxes, Brown Snakes, Skinks and Frogs.   g)   The organisms that are preys are Swamp Wallabies and Common Ringtail Possums. h)  The organisms competing for the same food are Animals 2 and 5 (Brown Snakes and Red Foxes).   i)   Increases: if the number of first order consumers were to increase there wouldn’t be any producers left. Decreases: if the number of first order consumers were to decrease the number of producers would increase, but the second and third order will be affected. j)  The first order would have a bigger population while the population of the second order would slowly decrease and may go extinct due to the lack of food.   k)   Some decomposers in my ecosystem are: -  Worms -  Sea Slaters l)  if the skinks population were to decrease the third order would also slowly decrease, seeing as though the skink is a second order, due to the lack of skinks.
