Chemical weathering and mechanical weathering can be influenced by plants. Plants contribute to mechanical weathering when their roots growth through cracks and crevasses in soil or rock. Overtime the roots will break rocks apart. Some plants produce and secrete organic acids that can change the chemical composition of rocks causing them to weather. Mechanical weathering breaks rocks into smaller pieces while chemical weathering changes the composition of the rocks.
