Hiya!
An ecosystem is an entire community of living things. They have life cycles, breathe, eat, etc., and all interact with one another. Non-living things, like rocks are dirt, are also a part of an ecosystem. Everything lives in one!
Unfortunately, humans can harm the ecosystem. Fossil fuels, non-renewable resources like coal and oil, killing of animals, and dumping toxic waste can and does harm the ecosystem.
If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer, if other people did not provide a helpful answer (but, I'm sure they did!). I want to be able to assist more users one-on-one! :)
