Why do the boreal forests see so little growth of smaller plant life on the forest floor?
a. They have a very short growth season and it is too cold the whole year for plants to grow.
b. The conifer trees block out the light making the forest floor too dark for plant life to survive.
c. Conifers do not drop their needles as often as leaved trees, and the needles decompose slowly so the soil is poor in nitrogen from lack of decomposed matter.
d. There is not enough rainfall to support anything other than the trees in the boreal forest.
