Take three test-tubes. Fill each of them with water. Label them A, B and C. Keep a snail in test-tube A, a water plant in test-tube B and in C, keep snail and plant both. Which test-tube would have the highest concentration of CO
2
Answers
Answer:
test tube A
Explanation:
In plants both respiration and photosynthesis take place,due to this reason the plants produce CO2 ( through respiration) and use it in photosynthesis and produce oxygen ( O2) so B could not be the answer. Now if we will talk about test tube C then snail will produce CO2 ( released as a product after respiration) and plant will use that CO2 ( produced by the snail) and CO2 produced by plant itself and will again change it into O2 ( due to the going on process photosynthesis) so again O2 will be produced hence the correct answer would be test tube A.
Answer:
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.
