C. Dams can displace organisms.

Building a dam can lead to the flooding of land, which can displace wildlife and destroy natural habitats. This can impact agricultural resources as wildlife plays a vital role in maintaining the balance of ecosystems that are beneficial for agriculture, such as pollination by bees and natural pest control. Displacement of organisms can also lead to loss of biodiversity and disruptions in the food chain, which can ultimately harm agricultural resources.
