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 interactions of photosynthesis and cellular respiration in the carbon cycle.
a photosynthesis uses carbon dioxide to produce glucose.
b cellular respiration uses the glucose produced in photosynthesis.
c cellular respiration releases carbon dioxide into the atmosphere.
d photosynthesis uses atp made in cellular respiration to fuel its reactions.
e photosynthesis released carbon dioxide which can then be used in cellular respiration.

Explanation:

• Option A: In photosynthesis, plants take in \(CO_2\) (carbon dioxide) and convert it into glucose (\(C_6H_{12}O_6\)) using light energy. The basic equation for photosynthesis is \(6CO_2 + 6H_2O

ightarrow C_6H_{12}O_6+6O_2\). So, this statement is correct.

• Option B: Cellular respiration is the process by which cells break down glucose (produced in photosynthesis) to release energy. The general equation for cellular respiration is \(C_6H_{12}O_6 + 6O_2

ightarrow6CO_2 + 6H_2O+\text{Energy (ATP)}\). So, this statement is correct.

• Option C: As shown in the cellular respiration equation (\(C_6H_{12}O_6 + 6O_2

ightarrow6CO_2 + 6H_2O+\text{Energy (ATP)}\)), carbon dioxide is a by - product of cellular respiration and is released into the atmosphere. So, this statement is correct.

• Option D: Photosynthesis uses light energy to produce ATP (during the light - dependent reactions), not ATP from cellular respiration. Cellular respiration uses the products of photosynthesis (glucose and oxygen) to make ATP for the cell's energy needs. So, this statement is incorrect.
• Option E: Photosynthesis consumes carbon dioxide (\(6CO_2 + 6H_2O

ightarrow C_6H_{12}O_6+6O_2\)), it does not release carbon dioxide. Cellular respiration releases carbon dioxide. So, this statement is incorrect.

Answer:

A. Photosynthesis uses carbon dioxide to produce glucose.
B. Cellular respiration uses the glucose produced in photosynthesis.
C. Cellular respiration releases carbon dioxide into the atmosphere.
