Quizplus · Accepted Answer

Alders are able to fix nitrogen in their roots through their symbiotic relationship with nitrogen fixing bacteria. This allows them to provide important nutrients to the soil and facilitate the growth of other plants in recently glaciated areas where the soil is nutrient-poor. This process is known as primary succession, which is the process of ecological succession that occurs in an area that is bare, lifeless, and uninhabitable. As such, the best answer is C - primary succession.
