Question

photosynthesis and cellular respiration are two of the primary processes involved in cycling carbon among the biosphere, atmosphere, hydrosphere, and geosphere. examine the model and choose all of the statements that accurately explain the role of photosynthesis in the carbon cycle. a photosynthesis stores carbon in the form of plants. b photosynthesis stores carbon in the form of glucose. c photosynthesis removes carbon dioxide from the atmosphere. d photosynthesis releases carbon dioxide into the atmosphere. e photosynthesis produces glucose that is then passed on as food to other organisms.

Explanation:

• Option A: During photosynthesis, plants take in carbon dioxide and convert it into organic compounds (like glucose). These organic compounds are stored in the plant. So, photosynthesis stores carbon in the form of plants (as they are made up of these carbon - based organic molecules).
• Option B: The chemical equation for photosynthesis is \(6CO_{2}+6H_{2}O

ightarrow C_{6}H_{12}O_{6}+6O_{2}\). Glucose (\(C_{6}H_{12}O_{6}\)) contains carbon, and it is synthesized from carbon dioxide. So, photosynthesis stores carbon in the form of glucose.

• Option C: The reactants of photosynthesis include carbon dioxide (\(CO_{2}\)). Plants take in \(CO_{2}\) from the atmosphere as part of the photosynthesis process. So, photosynthesis removes carbon dioxide from the atmosphere.
• Option D: Cellular respiration (not photosynthesis) releases carbon dioxide into the atmosphere. The equation for cellular respiration is \(C_{6}H_{12}O_{6}+6O_{2}

ightarrow6CO_{2}+6H_{2}O\). So, this option is incorrect.

• Option E: Plants (producers) produce glucose through photosynthesis. Herbivores eat plants, and then carnivores eat herbivores. So, the glucose (which contains carbon) produced by photosynthesis is passed on as food to other organisms.

Answer:

A. Photosynthesis stores carbon in the form of plants.
B. Photosynthesis stores carbon in the form of glucose.
C. Photosynthesis removes carbon dioxide from the atmosphere.
E. Photosynthesis produces glucose that is then passed on as food to other organisms.
