Answer 1

Answer:

CO, this is correct ans

Answer 2

Answer:

The CO

2

is generated because of respiration by snail. Snail is an organism that breaths in O

2

and breaths out CO

2

. Hence,CO

2

concentration increases in test tube A.

Test tube B contains a water plant, which takes in CO

2

for photosynthesis and gives out O

2

. Hence, more O

2

concentration is seen in test tube B.

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

2

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

2

released by the plant is utilized for snails respiration.

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