Moderate temperatures and precipitation, as well as nutrient-rich soil due to annual leaf fall, characterize this biome.
a) temperate grassland
b) taiga
c) deciduous forest
d) temperate coniferous forest
e) savannah

The correct answer is c) deciduous forest

Explanation:

Deciduous forest is the forest that is dominated by deciduous trees that shed their leaves annually. These forests are found in temperate climates having moderate temperature. They are found in eastern Canada and United States, Europe, China, and Japan.  

In deciduous forest, precipitation is moderate and quite constant overall which ranges between 75-150 cm. The soil in deciduous forest is nutrient-rich as the decomposition of fallen leaves release all the nutrients into the soil. So the correct answer is c) deciduous forest.
