5 0

Answer:

<u>A.  Building dams, deforestation cutting down trees), adding point sources to nearby streams to allow for run-off, building roads and structures, and salting roads.</u>

Explanation:

Removing non-native species from the environment helps the native ants to thrive without having any changes in the ecosystem effect them (i.e. new invasive animal).

Creating laws to prohibit fishing from local streams helps keep the fish alive and allowing them to continue to use this stream.

Planting trees and other plants to attract native species helps secure and grow the ecosystem of that area.

<em>This leaves </em><em>A</em><em> </em><u><em>as the answer.</em></u>
