   Within a lake, which is an example of an ecosystem, there may be populations of frogs, bass, insects (called water striders), and water lilies. Each species of organism has its own place in the habitat in the pond; the frogs in the shallow region, the bass in the deep water, the water strider on the surface, and the water lilies in the shallow region near the shore.
