Explanation: What does your backyard have in common with the Pacific Ocean? It's hard to imagine that they could possibly have anything in common, right? Well, they are both ecosystems. They both have living organisms and non-living factors such as animals and oxygen. An ecosystem is a group of living organisms and the environment that surrounds them. They can be as small as a puddle or as large as the entire earth. Ecosystems can be natural, like your backyard, or artificial, such as an aquarium.
