How do ecosystems change?

The most common way that humans damage ecosystems is by destroying habitat. For example, we remove trees, change the flow of water, and change grasslands into farms.

How do ecosystems change over time?

Ecosystems, the interactive system of living and nonliving organisms in a specific location, change slowly over time. When new plants and animals arrive in an area, they either thrive or struggle. Thriving species sometimes displace native species. When this happens, the system as a whole begins to change.
