4 Summary

An ecosystem is the delicate state of balance between living and nonliving things in a particular environment. If a part of an ecosystem is removed or altered, the existing harmony will be offset and the entire system will go through a change, large or small, positive or negative. The understanding of ecosystems provides a strong foundation for studying the environment. Understanding the interconnectedness of things in an ecosystem provides a basis for respecting the significance of each of the different parts of the surrounding environment.
