Question
The graph shows the levels of dissolved carbon dioxide in the environment of an aquatic plant over a 24-hour period.
The shaded portion of the graph represents a part of the daily cycle of the plant. Which of the following is happening during that time?
Options
The plant switches from photosynthesis to metabolizing glucose.
The plant is producing glucose at the highest levels of the day.
The rate of photosynthesis is increasing due to increased sunlight.
Levels of dissolved oxygen are increasing at a similarly rapid rate.

Based on the description provided and the context of an aquatic plant's daily cycle, the shaded portion of the graph likely corresponds to a time when the levels of dissolved carbon dioxide are changing in relation to photosynthesis.
Typically, during the day when sunlight is abundant, plants engage in photosynthesis at a higher rate, consuming carbon dioxide and producing glucose and oxygen. If the shaded portion represents a time of increased dissolved carbon dioxide, this could be favorably linked to the plant operating at its peak photosynthetic activity.
Considering the options, the most fitting statement describing what is likely happening during the shaded time would be:
**The rate of photosynthesis is increasing due to increased sunlight.**
This aligns with the expectation of an aquatic plant utilizing available light for photosynthesis, leading to changes in carbon dioxide levels during the day.
