Explanation:

1. Labeling the Gases for Photosynthesis and Respiration

• Photosynthesis: Plants use carbon dioxide ($\ce{CO_2}$) and water to produce glucose and oxygen ($\ce{O_2}$) in the presence of light. The gas taken in is carbon dioxide, and the gas released is oxygen.
• Respiration: Organisms (including plants and animals) use oxygen to break down glucose, releasing energy, carbon dioxide, and water. The gas taken in is oxygen, and the gas released is carbon dioxide.

So, if one box is for the gas needed to survive (for respiration, we need oxygen; for photosynthesis, plants need carbon dioxide, but for most organisms’ survival, oxygen is essential for respiration), and the other relates to the gas exchange:

• If the hint is about “what gas you need to survive” (respiration), the gas needed is oxygen ($\ce{O_2}$), and the gas produced by photosynthesis (and used in respiration) or exchanged: photosynthesis takes in $\ce{CO_2}$ and releases $\ce{O_2}$; respiration takes in $\ce{O_2}$ and releases $\ce{CO_2}$.

Assuming the boxes are for the two main gases:

• One box (for the gas needed to survive, e.g., for human/animal respiration) is Oxygen (needed for cellular respiration to produce energy).
• The other box (related to photosynthesis and the gas exchanged) would be Carbon Dioxide (taken in by plants for photosynthesis, released by respiration).

2. Possible Answer for “What is a possible…” (Incomplete, but assuming context like “What is a possible reason for…”)

If the question is about a possible reason for gas exchange or survival:

• A possible reason organisms need gas exchange (respiration) is to obtain oxygen for cellular respiration (to produce ATP, energy) and release carbon dioxide (a waste product of respiration).
• For photosynthesis, plants need gas exchange to take in carbon dioxide (for glucose production) and release oxygen (a byproduct).

Final Answers (for Labeling):

• Gas needed to survive (respiration): $\boldsymbol{\ce{O_2}}$ (Oxygen)
• Gas exchanged in photosynthesis/respiration: $\boldsymbol{\ce{CO_2}}$ (Carbon Dioxide)

(Note: The exact labels depend on the diagram’s boxes, but the key gases are $\ce{O_2}$ and $\ce{CO_2}$ for the two processes.)

Answer:

• Photosynthesis: Plants use carbon dioxide ($\ce{CO_2}$) and water to produce glucose and oxygen ($\ce{O_2}$) in the presence of light. The gas taken in is carbon dioxide, and the gas released is oxygen.
• Respiration: Organisms (including plants and animals) use oxygen to break down glucose, releasing energy, carbon dioxide, and water. The gas taken in is oxygen, and the gas released is carbon dioxide.

2. Possible Answer for “What is a possible…” (Incomplete, but assuming context like “What is a possible reason for…”)

If the question is about a possible reason for gas exchange or survival:

• A possible reason organisms need gas exchange (respiration) is to obtain oxygen for cellular respiration (to produce ATP, energy) and release carbon dioxide (a waste product of respiration).
• For photosynthesis, plants need gas exchange to take in carbon dioxide (for glucose production) and release oxygen (a byproduct).
