Why does water level increases in germinating seed experiment?

KOH is a good absorbent.
KOH absorbs the carbon dioxide released by the germinating seeds and a partial vacuum is created because of the loss of carbon dioxide in the flask.
This vacuum causes the water level in the delivery tube to rise up.
Germinating seeds are used because they use up the oxygen in the flask to respire and release carbon dioxide as a result, which is absorbed by KOH, causing the weight of KOH to increase
