How does the total amount of phosphorus in an ecosystem change over the course of primary succession?
The total amount of phosphorus in an ecosystem decrease over the course of primary succession, while secondary succession occurs when the disturbance affects community without making changes to the soil..
Primary succession occurs when the occurred disturbance significantly modifies the newly exposed geological substrates but not modified by organisms. Succession at Glacier Bay results in changes such as increased soil depth, increased organic content and moisture, decreased soil bulk density and phosphorus concentration.
