b. The amount of CO2 be the lowest in which one and why?

please answer ​

Answer 1

Explanation:

the amount of co2 is highest

because there are plant in jar

when rat taking release carbon dioxide inhale oxygen from plant

plant releasing oxygen

Answer 2

The answer to the questions are :

1. The highest amount of CO2 is in the third jar. The third jar contains 3 rats who use oxygen for respiration and release carbon dioxide. This jar doesn't contain a plant like the other two jars which can utilise the released carbon dioxide.
2. The lowest amount of CO2 is found in the first jar. This is because the first jar only contains a plant that uses carbon dioxide during photosynthesis and releases oxygen. In the next two jars, some rats use the oxygen for respiration and release carbon dioxide but this jar doesn't have it. So this jar has the lowest level of carbon dioxide from the there jars.
