What is an ecosystem?

An ecosystem is a community of living organisms (plants, animals, and microorganisms) interacting with each other and their physical environment (such as soil, water, and air). These interactions create a complex web of relationships and dependencies that help to maintain the balance and health of the ecosystem. Ecosystems can vary in size and complexity, ranging from a small pond to a vast rainforest.

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and soil), interacting as a system. Ecosystems are found everywhere on Earth, from the tops of mountains to the bottom of the sea. Each ecosystem is unique, but all ecosystems share some basic characteristics.
