Detailed explanation-1: -Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome.

Detailed explanation-2: -Tropical Forest Biomes Climate in these biomes shows little seasonal variation (Figure 5), with high yearly rainfall and relatively constant, warm temperatures. The dominant plants are phanerophytes-trees, lianas, and epiphytes.

Detailed explanation-3: -Temperate grasslands are characterized by a rich mix of grasses and underlaid by fertile soils. Periodic fires and heavy grazing by large herbivores maintain the characteristic plant community.

Detailed explanation-4: -Tropical grasslands have dry and wet seasons that remain warm all the time. Temperate grasslands have cold winters and warm summers with some rain. The grasses die back to their roots annually and the soil and the sod protect the roots and the new buds from the cold of winter or dry conditions.
