Hlo!!
The possible reasons can be:-
1)set up should be air tight
2)lime water is to be prepared fresh
3)dead seeds are to be coated with antiseptics otherwise , the baacteria will perform anaerobic respiration.

Hey there! Hope this helps you
The rise in the level of water indicates that CO2 is produced by germinating seeds during respiration. Actually, the germinating seeds respire and produce CO2, which is absorbed by KOH solution. This creates a vacuum in the conical flask. The air present in the bent glass tube moves into the conical flask. This pulls the water in the bent tube further up.
Possible reasons:
1. the conical flask airtight.
2. Fix the shorter end of the glass tube in such a way that it does not touch the seeds.
3. Use freshly prepared KOH solution.
