answer in one word​

Answer 1

Answer:

Outside air is only passed inside though air pump via soda lime in flask A (absorbs CO2 in air). As the air leaves the jar, it passes through lime water in flask B. CO2 being heavier than air would flow down into the test tube turning limewater milky. Thus, carbon dioxide is produced by green plants during respiration.
