What are difference and similarities between communities and ecosystem?

Answer 1

difference: communities are only a group of all the populations of living organisms in a region, while ecosystems are interactions between biotic and abiotic organisms in the environment.

Answer 2

Communities are groups of interacting populations of different species in a specific area, while ecosystems include both the living and non-living components of a specific area interacting with each other. Both communities and ecosystems involve different organisms coexisting and interacting with each other, but ecosystems also include the physical environment as a crucial component.
