LATITUDE
The differences between biomes can also be caused by latitude, and where they are located in relation to the Equator, the temperature would vary depending in which angle is receiving the sunlight. For example, biomes located in the high latitudes, farthest from the Equator like taiga and tundra receive the least amount of sunlight and have lower temperatures, and biomes located at middle latitudes between the poles and the Equator are like temperate deciduous forest and temperate grasslands, these two, receive more sunlight and have moderate temperatures. At the low latitudes of the Tropics the sun's rays strike the Earth most directly, as a result, the biomes located there receive more sunlight and have higher temperatures, like tropical rain forest and tropical grassland.
