How do you use a natural ecosystem?
We don't spend a lot of time in natural ecosystems because where ever we are, chances are the biotic and abiotic factors has been changed. They change becuase humans changed it. When humans change the ecosystem it is no longer a natural ecosystem. We use natural ecosystems and turn it into thing's like golf courses, housing area's etc. So basically we are in non natural ecosystems most of the time. But the only time we do use (or are in) a natural ecosystem in when we are in/by a forest, pond (that was naturally made) etc. Hope that helped :)
