What Is an Ecosystem?
Grade 3 · Science · Ecosystems · Alberta, Canada
Lesson Summary
An ecosystem is a community of living things and the nonliving things around them, all working together.
Explanation
An ecosystem includes all the plants, animals, and tiny organisms in an area, plus the nonliving things like water, soil, air, and sunlight. A pond is an ecosystem: fish, frogs, plants, water, and mud all interact. A forest is another ecosystem. Living and nonliving parts depend on each other. If one part changes, it can affect everything else in the ecosystem.
