Question:

True/false question

Leaf area increases with stand age, resulting in a decreasing rate of photosynthesis in the stand.

Answer hidden

Response:

User answerFeedback
True

An increment in leaf area increases also the photosynthesis of a tree stand. However, the relationship is saturating.
