🇬🇧🇨🇳 ecosystem - 生态系统 : English Lesson

Meaning of "ecosystem" ("生态系统"), detailed definition, and a short video lesson below.

An ecosystem is like a giant neighborhood where plants, animals, and tiny germs all live together and affect each other. In an ecosystem, the soil, water, air, sunlight, plants, and animals are all connected. If one part changes—like if there’s less water or fewer insects—it can change the whole ecosystem. A pond, a forest, a desert, or even your backyard can be an ecosystem, with all the living things and their home working together like one big team.
