Question

you have taken three test tubesyou have taken 3 test tubes filled with water in test tube a you placed a snail in test tube b you placed a water plant in tast tube c you placed aboth snail and water plant now which tube contain more Co2. give reason​

Answer 1

I THINK IN TEST TUBE B BECAUSE SNAIL WILL BREATHE AND PRODUCE CO2

WHERE AS IN TEST TUBE C SNAIL WOULD NOT BE ABLE TO BREATHE IN WATER

Answer 2

Test tube A will have the highest concentration of CO2. This is because test tube A contains snail. Snail is an organism that breathes in O2 and breathes out CO2. Hence, CO2 concentration increases in test tube A.

Test tube B contains a water plant, which takes in CO2 for food synthesis and gives out O2. Hence, more O2 concentration is found in test tube B.

Test tube C contains both a snail and a plant. The CO2 produced by the snail is utilized by the plant for its food synthesis and the O2 released by the plant is utilized by the snail for respiration.

Therefore, test tube A has the highest concentration of CO2.
