उत्तर
- Jar ‘C’ will have the highest amount of CO2. It is because the mice kept in the jar will exhale CO2 continuously by breathing and thus, increasing its amount in the bell jar.
- Jar ‘A’ will have the least amount of CO2. It is because, in this jar, CO2 released during respiration by the plant is used during photosynthesis.
