A)weathering and erosion of park pathways
B)deterioration of the man-made structures in the park
C)pattern and timing of leaf loss in the shade trees
D)exposure of rocks and minerals found in the soil
The only effect, out of this options, that would be studied by biologists is the "pattern and timing of leaf loss in the shade trees".
