Final answer:
Cold temperatures slow down nutrient cycling in boreal forests.
Step-by-step explanation:
The characteristic that slows down nutrient cycling in boreal forests is cold temperatures. Boreal forests are located in high-latitude regions with long, cold winters. These cold temperatures limit the activity of decomposers, microorganisms, and nutrient cycling processes. As a result, organic matter decomposition is slower, leading to slower nutrient cycling in boreal forests.
