density - independent
done

Explanation:

Density - independent limiting factors affect populations regardless of their density. Dams can cause habitat destruction, change water flow, and impact species survival in a way that is not related to the population density of the affected organisms. For example, a dam can flood an area and wipe out a species' habitat regardless of how many individuals of that species are present.
