This chapter describes some of the major terrestrial biomes in the world; tropical forests, savannas, deserts, temperate grasslands, temperate deciduous forests, Mediterranean scrub, coniferous forests, and tundra (Figure 4).

Detailed explanation-3: -Terrestrial biomes or land biomes – e.g. tundra, taiga, grasslands, savannas, deserts, tropical forests, etc. Freshwater biomes – e.g. large lakes, polar freshwaters, tropical coastal rivers, river deltas, etc. Marine biomes – e.g. continental shelf, tropical coral, kelp forest, benthic zone, pelagic zone, etc.

Detailed explanation-4: -Arctic tundra are found on high-latitude landmasses, above the Arctic Circle-in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, for example-or on far southern regions, like Antarctica. Alpine tundra are located at very high elevations atop mountains, where overnight temperatures fall below freezing.
