Answer 2

Explanation:

The test tube A will have the highest concentration of carbon dioxide. The carbon dioxide(CO

2

) comes because of respiration by the snail. Snail is an organism that breaths in O

2

and breaths out (CO

2

).Hence,(CO

2

concentration increases in test tube A.

The test tube B contains a water plant, which takes is (CO

2

) for photosynthesis and gives out O

2

.Hence, more O

2

concentration is seen in test tube B.

The test tube C contains both snail and a water plant. The CO

2

) produced by the snail is utilized by the plant for the photosynthesis and the O

2

released by the plant is utilized for snails respiration.

Therefore The test tube A will have the highest concentration of carbon dioxide.
