Ecosystem Quizzes & Trivia

The ecosystem concept is the idea that living organisms interact with every other element in their local environment. Any unit that includes all of the organisms (ie: the "community") in a given area interacting with the physical environment so that a flow of energy leads to clearly defined trophic structure, biotic diversity, and material cycles (ie: exchange of materials between living and nonliving parts) within the system is an ecosystem.
