Answer:
Warm and wet climate
Step-by-step explanation:
The average temperature during summers in deciduous forest is 70 degree Fahrenheit while the average temperature during summers in coniferous forest is 50 degree Fahrenheit.
In deciduous forests there are four seasons : winter, summer, autumn , monsoon. Due to such varied climate variation, the deciduous' forest temperature varies between cold to hot wet summers. Wet and hot summer is an advantageous scenario to propagate decay of organic matter.
Due to this climatic variation organic matter decay more rapidly in deciduous forests than in coniferous forests
