b) The temperature of the water in the lakes has increased because of human inflicted global warming.



c) There is little water entering the Lake Victoria, especially in dry weather. This is because the Thompson dam reduces the flow of fresh water thats used for Melbournes' water supply.



d) There have been algal booms in the lake ecosystem because the waters temperature has increased and phosphates, this creating the perfect coonditions for them produce and grow.



e) The reason the lakes have dried up is because of the dying plants, this causing the water way to silter.
