Understanding Ecosystems and Their Functions

The video introduces ecosystems as communities of living things in habitats, comparing them to neighborhoods where animals, plants, and weather interact. It explains two main types: terrestrial (land-based) and aquatic (water-based). Terrestrial ecosystems include forests, grasslands, tundra, and deserts, while aquatic ecosystems cover freshwater and marine environments. The video highlights the functions of ecosystems in maintaining environmental stability, recycling nutrients, and balancing plant and animal life. It concludes with a call to action for viewers to subscribe and learn more.
