Question

Quizplus · Accepted Answer

PAR is greatest during the summer in a temperate deciduous forest due to the abundance of sunlight and longer days. As the trees are full of leaves, they can intercept a greater amount of solar radiation and convert it into energy through photosynthesis. During fall, the leaves start to change color, and during winter, many trees lose their leaves, resulting in less interception of sunlight and lower levels of PAR. In the spring, while there may be an increase in PAR, it is not typically as high as during the summer.
