Answer:
The given statement is false.
Tropical rainforests are located near the equator and receive precipitation generally in the form of rain. These forests receive a large amount of precipitation throughout the year which can range from 80 inches to 400 inches in a year.  
Temperate rainforests are located on higher altitudes as compared to the tropical rainforests. They receive precipitation in the form of rain and snow. They receive less amount of rain as compared to tropical rainforests. They receive precipitation which lies between 40 inches and 60 inches in a year.
Thus the amount and type of precipitation in tropical and temperate rainforests are different.
