Carbon Entry & Transport In Wetlands

Question 0

The other half of the GPP is oxidised by the plant for energy (respiration) and released as

Answer 0

Carbon dioxide through the leaves into the atmosphere and through the roots into the soil solution as DIC.

Question 1

Photosynthesis by vegetation causes carbon to be drawn from the

Answer 1

Local atmosphere and converted to organic carbon. This is the GPP. About half of the carbon fixed in PS becomes plant tissue.

Question 2

The roots can release DOC into both

Answer 2

Aerobic and anaerobic soil solutions.

Question 3

DOC and DIC can enter wetland from surrounding areas in

Answer 3

Groundwater, through flow or flood water.

Question 4

The death of leaves and plants adds large amounts of

Answer 4

POC to aerobic and anaerobic soil solutions.

This is nearly the total amount of carbon that has been fixed over the growing period.

Question 5

POC can be transported to wetlands from

Answer 5

Other areas such as floodplain wetlands.
