Question

describe how plant acids contribute to the weathering of rocks and provide an example from the images.

Explanation:

Plants release organic acids through their roots. These acids can chemically react with minerals in rocks, breaking them down. For example, when roots secrete acids like carbonic acid, it can dissolve calcium - carbonate in limestone rocks, leading to weathering. Without seeing the specific images, a general example could be roots of trees growing in cracks of rocks, secreting acids that contribute to the widening and breaking of rocks over time.

Answer:

Plant roots secrete organic acids that chemically react with rock - forming minerals, causing weathering. An example could be roots of trees in rock cracks secreting acids that break down limestone.
