The Food Cycle and Food Chains 1963 Acceso gratuíto e ilimitado
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.
