Deciduous Trees in North America are Dormant During Winter Months

Question

Deciduous trees in North America are dormant during winter months because ____.  
A) they receive no precipitation during winter
B) photosynthesis cannot occur during winter
C) this offers a way to survive the extended drought-like conditions
D) the cold temperatures would otherwise damage leaves and buds
E) they have no leaves during winter months

Accepted Answer

The cold temperatures during winter can damage leaves and buds of deciduous trees, so they enter a state of dormancy to protect themselves. During dormancy, the tree conserves energy and reduces water loss, allowing it to survive the extended drought-like conditions.
