Ecosystem Types and Characteristics

The video, presented by Asha, explores the classification of ecosystems into natural and man-made categories. Man-made ecosystems, such as botanical gardens and aquariums, are created and maintained by humans. Natural ecosystems are further divided into aquatic and terrestrial types. Aquatic ecosystems include marine and freshwater environments, with examples like coral reefs and estuaries. Terrestrial ecosystems encompass grasslands, deserts, forests, and mountains. The video emphasizes the complexity of natural ecosystems compared to the simpler man-made ones and encourages viewers to share and subscribe.
