Q.Classify the aquatic biomes of Earth.

A biome is a large region unified by shared climate, soil, and characteristic flora and fauna, broader than a habitat (a single biome contains many habitats). Biomes are defined by their geographic position, climate, and dominant plant/animal life, with boundaries between adjacent biomes often forming gradual transition zones rather than sharp lines (e.g., between grassland and forest). Broadly, biomes are aquatic (about 71% of the biosphere: freshwater, brackish water, marine) or terrestrial, distinguished chiefly by dominant vegetation and set mainly by regional climate. Major terrestrial biomes are Tundra (treeless, permafrost, long dark winters, dwarf vegetation, migratory herbivores like reindeer), Taiga (a coniferous forest belt south of the tundra, home to moose and timber wolves), Grassland (hot summers, cold winters, irregular rainfall, grazing herbivores), Alpine (the high-elevation zon …
