What is in an ecosystem that is not in a community?

Have you defined an ecosystem and a community? So think about it in our world terms. A community would be the people we live with right? And the ecosystem, well that would include other species like our pets and the surrounding plants. There’s a major difference between the two, can you spot it in my example?

It is evolution, because we all have some of the same traits like eye color or shape or ears.
