Why we use snail and plant in test tube for photosynthesis?
Answers
The similarities and differences between aerobic and anaerobic respiration are as follows:
Similarities: Food is oxidized in both cases and energy is released.
Differences: Carbon dioxide and water are the end products of aerobic respiration, while alcohol or lactic acid is the end product of anaerobic respiration. Aerobic respiration is more efficient than anaerobic respiration.
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.
