Food webs are illustrated, the abiotic-producer-consumer-decomposer cycles, problems of acid rain and pond succession are also stressed.
The largest chain of fresh water lakes in the world has special ecological problems of its own. This live-action video explains some of the challenges today. Stressed are the sea lamprey, toxic wastes in the lakes, the coming of the zebra mussel and the ruffe fish.
