Ecosystem Types and Characteristics

The video tutorial explains the classification of ecosystems into natural, artificial, and incomplete categories. Natural ecosystems are further divided into aquatic and terrestrial types, with aquatic ecosystems including freshwater, marine, and estuarine ecosystems, and terrestrial ecosystems comprising forest, grassland, desert, tundra, and polar ecosystems. Artificial ecosystems are those influenced by human activity, while incomplete ecosystems lack one or more essential components.
