Ecosystem Exploration From Tundra To Taiga

The video tutorial introduces ecosystems, which consist of living and non-living components in a specific area. It categorizes ecosystems into terrestrial and aquatic types. Terrestrial ecosystems include tundra, taiga, deciduous forest, grassland, desert, and rainforest, each with unique climates and food webs. Aquatic ecosystems are divided into freshwater, saltwater, and brackish water, with diversity influenced by salinity and temperature. The video explains the characteristics and food chains within these ecosystems.
