How do ecosystems change overtime?
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.
What types of change could affect an ecosystem?
