Question

What is the correct order of existence of biomes while moving from the equator to the North Pole?

A. Tropical rain forests 🡪 deserts 🡪 taiga

B. Tundra 🡪 deserts 🡪 grasslands

C. Grasslands 🡪 tundra🡪 rain forests

D. Temperate deciduous forests 🡪 taiga 🡪 rainforests

E. Tropical rain forests 🡪 taiga 🡪 grasslands 🡪 tundra

Answer 1

Hint: A biome is a large area which is identified by its vegetation, climate, soil and biodiversity. The terrestrial biome is of seven types- tundra, shrub land, rainforest, grassland, desert, temperate deciduous forest, coniferous forest.

Complete Answer:

- Biome is the climatic condition or the environmental condition of the large geographic area in which the community of organisms live. Their distribution around the globe is somewhat predictable. The biomes are classified into terrestrial biomes which includes tundra, taiga, grasslands, savannas, desert, and tropical rainforests.

- The factors which influence the biome are proximity to the equator, temperature, precipitation, geography of land, climate etc.

- Proximity to the equator- The biome at higher latitudes i.e. far away from the equator is cooler and drier. The biomes which are closer to the equator are generally warmer and wetter. The moisture content of warmer air is greater than that of cooler air.

Geographical distribution

- Moving from the equator towards the pole, the biomes found are tropical rainforest, temperate grasslands or the cold deserts, taiga, and tundra.

So, the correct answer is option A, Tropical rain forests 🡪 deserts 🡪 taiga

Note: The taiga is the world’s largest land biome of the world whereas tundra is the coldest of all the biomes. The tundra region is like a desert as it receives very less rainfall. It is found just below the icecaps of the Arctic.
