Question

Observe Figure 10.1 carefully and answer the following questions.

  1. In which jar, will the amount of CO2 be the highest and why?
  2. In which jar, will the amount of CO2 be the lowest and why?
Answer in Brief

Solution

  1. Jar ‘C’ will have the highest amount of CO2. It is because the mice kept in the jar will exhale C02 continuously by breathing and thus, increasing its amount in the bell jar.
  2. 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.
