Forests are responsible for storing large amounts of carbon. However, there are some

atmosphere. When does this typically occur? A. trees release carbon when decaying,
so when areas experience deforestation large amounts of a forest's sequestered carbon
will be released back into the atmosphere. B. trees release large amounts of carbon
during the process of photosynthesis, in vast forests of broadleaf trees this outweighs
the amount of carbon sequestered - Answers - Trees release carbon when decaying, so
