$\huge\mathcal\colorbox{blue}{{\color{white}{AŋʂᏯɛཞ࿐}}}$

Some germinating seeds are taken in the bulb and mouth of the bent tube is kept immersed in a beaker containing caustic potash(KOH) solution. ... The caustic potash absorbs the CO2 and a vaccum is created. So the KOH solution rises in the tube. This proves that CO2 is liberated during respiration.

Answer 2

Answer:

Because, KOH removes the carbon dioxide and oxygen is used by cellular respiration thus decreasing the volume of gas in respirometer.
