Energy Transfer in Ecosysteh You might think of a pond as a quiet and peaceful place to enjoy nature. A pond may seem quiet, but many interactions are taking place at all times. Plants that live within and around the pond use energy from the sun to make food. Ducks, herons, and other birds visit the pond to bathe, nest, and feed on the plants and animals in and around the pond. Fish, dragonfly larvae, and frogs hunt prey in the shallow water. Raccoons prowl for a meal on the shore. Microbes and earthworms break down nonliving plant and animal matter. By doing so, they return nutrients to the muddy soil of the pond. A pond, a desert, or a forest is an ecosystem, a complex organization of interdependent parts. Every ecosystem involves the flow of energy and cycling of nonliving resources through a web of producers, consumers, and decomposers. 2. Label the organisms in this pond ecosystem as a producer, consumer, or decomposer.
