To survive, humans need to breathe in oxygen (O2). Oxygen is essential for cellular respiration, a process that generates energy in our cells. While nitrogen makes up about 78% of the air we breathe, it does not play a role in this process.

Where is this gas produced? 1 sentence
Oxygen is primarily produced through photosynthesis by plants, algae, and some bacteria, which convert carbon dioxide and water into glucose and oxygen using sunlight.
. Hypothesize what the bubbles in the tank on the Gizmo represent 1 sentence
The bubbles in the tank on the Gizmo likely represent the release of oxygen produced during photosynthesis as plants convert carbon dioxide and water into glucose and oxygen.
How does oxygen production relate to the rate of photosynthesis half a sentence no extra details
Increased oxygen production typically indicates a higher rate of photosynthesis.
How do you think light intensity affects the rate of oxygen production? half a sentence no extra details
Higher light intensity generally increases the rate of oxygen production during photosynthesis.
How do you think temperature affects the rate of oxygen production? half a sentence no extra details
Temperature affects the rate of oxygen production by optimizing enzymatic activity, with moderate temperatures typically enhancing photosynthesis until extreme heat or cold inhibit it.
