My science text says to make sure students can differentiate between environment and ecosystem, and suggests having them make a chart of similarities and differencies if they are struggling. However, I'm confused and having a hard time telling the difference between the terms. These are some sentences from the book: "An environment is everything that surrounds a living thing. The nonliving parts of an environment support the living things in the environment." "An ecosystem is all the living and nonliving things in an environment." "In an environment, living and nonliving parts act on each other or interact. These interacting parts make up an ecosystem. The living parts of an ecosystem depend on nonliving parts." Is it just me, or are all of these saying the same thing? Am I missing something because of the 3rd grade level? What is the difference between these two vocabulary words? Help!!!!
