3. What is the dependent variable of the graph? What unit is used to measure it?

• Temperature of Water, measured in °C.
• pH is measured from 0 to 14.

• DO and CO₂ are measured by how much is in the water

• The dependent variables are Dissolved Oxygen level (DO), Carbon Dioxide (CO₂), and pH.

What is the independent variable of the graph? What unit is used to measure it?

• time of day, It’s measured by parts of the day, like morning, noon, afternoon, and midnight.

• distance, measured in meters

• speed, measured in km/h

• temperature, measured in Celsius

What is the label on the x-axis?

• Time of day

• Distance

• Speed

• Temperature

What are the labels on the y-axis?

• Dissolved Oxygen, Carbon Dioxide, pH Value
• Salinity
• Temperature
• Nutrient Levels

When is the carbon dioxide the highest and why?

• During the day due to photosynthesis

• Carbon dioxide is highest around midnight and early morning. This is because plants are not doing photosynthesis at night.

• In winter due to increased heating

• In summer due to increased respiration

When is the oxygen the highest and why?

• During the day because of photosynthesis

• At night because of reduced consumption

• In the morning due to dew formation

• In the evening due to cooling temperatures

Oxygen and carbon dioxide are related through the process of:

• Photosynthesis and respiration

• Evaporation and condensation

• Fusion and fission

• Oxidation and reduction
