Final answer:
Photosynthesis is not associated with biological weathering, which involves the breakdown of rocks and minerals by living organisms.
Step-by-step explanation:
Biological weathering refers to the breakdown of rocks and minerals by the actions of living organisms. Photosynthesis, while a critical biological process where plants convert light energy into chemical energys, does not directly contribute to the breaking down of rocks or contribute to weathering. In contrast, processes such as wedging by roots, ion exchange by lichens, the burrowing of animals, and the wetting and drying of lichens are all examples of biological factors that contribute to the weathering of rocks.
