This is a documentary about the fragile and complex marine ecosystem in the Bay of Fundy. The film traces relationships within the food chain - from tiny plankton to birds and seals and finally to whales and humans. The film is a plea for careful management of our ocean resource and was first telecast as part of CBC's Nature of Things series.
Uses animation and live action photography to describe good food chains, almost all depending ultimately on green plants, and relates these food chains to the larger concepts of the oxygen-carbon dioxide and the nitrogen cycles, and to the unending pattern of life, growth, and decay which is known as the food cycle.
PRIMAVERA is a three dimensional film featuring puppets that work in the so called telescope system which tries with the help of stylised images to visually depict the great variety existing in nature, the food chain and variations in the reproduction of different living organisms. The entire film is seen through the eyes of a butterfly larva.
Three invertebrates - a water flea, a green hydra, and a planarian flatworm - engage in a food-chain fight after the hydra tries to eat the flea.
