Answer and Explanation:
In the case when you move outwards from a tree so there would be more growth, the reasons are as follows:
1. The block i.e. left and light near tree permits lesser photosynthesis as in the tree
2. But if you move outwards so there would be more light
3. Also it permit plants to photosynthesis that generates greater amount of glucose and proteins for growth
In this way it would be explained

The dark reaction of photosynthesis is called the Calvin cycle or Calvin -  Benson cycle.
It is a series of  chemical reactions that occur in chloroplasts during photosynthesis.
It is also known as the light - independent phase because it happens after  light energy ahs been absorbed from the sun.
It is named after  scientist called Melvin Calvin who was the winner of a Nobel prize in chemistry for finding how this cycle works way back in 1961, at the university of California.
