An ecosystem is a community of living things (plants, animals, and microorganisms) that interact with each other and their non-living environment (like air, water, and soil). These interactions create a delicate balance, where energy and nutrients are constantly cycling. Understanding ecosystems helps us appreciate the interconnectedness of life on Earth!
