Identify the property of the dung that made it useful.

To answer this question, I need more context. The usefulness of dung can vary greatly depending on the context. For example, in agriculture, the nutrient-rich nature of dung makes it a valuable fertilizer. In some cultures, dried dung is used as a fuel source due to its combustibility. In certain ecosystems, dung can play a crucial role in dispersing seeds and nutrients. So, the property of dung that makes it useful can be its nutrient content, its combustibility, or its role in seed and nutrient dispersal, among others.
