Detailed explanation-1: -There are five major types of biomes: aquatic, grassland, forest, desert, and tundra, though some of these biomes can be further divided into more specific categories, such as freshwater, marine, savanna, tropical rainforest, temperate rainforest, and taiga. Aquatic biomes include both freshwater and marine biomes.

Detailed explanation-2: -There are eight major terrestrial biomes: tropical rainforests, savannas, subtropical deserts, chaparral, temperate grasslands, temperate forests, boreal forests, and Arctic tundra.

Detailed explanation-3: -In the terrestrial category, 7 biomes include tropical rainforests, temperate forests, deserts, tundra, taiga – also known as boreal forests – grasslands and savanna.

Detailed explanation-4: -There is general agreement among ecologists that our complex natural world can, based on temperature and rainfall, be classified into six major biomes: desert, tundra, grassland, coniferous forest, deciduous forest, and tropical forest (Odum, 1989).
