Question:
Do trees produce oxygen in the winter without any leaves? Do evergreen trees produce oxygen?


Replies:
Evergreen trees such as pine, spruce, cedar, and fir produce oxygen in the winter.

Deciduous trees lose the leaves that they use for making oxygen during the growing season. However, there are some cases of trees with green twigs or green bark which can still make oxygen during the winter.
