This carbon dioxide molecule with the arrow pointing at it, is named Henry.

Today, we will go on an adventure with him, though his job everyday.

Currently, Henry has no energy, like most in-organic things in the atmosphere.

Carbon dioxide is a molecule of two oxygen, and one carbon. It is a waste product of Cellular Respiration.

As you can see, Henry is nearing the plant. Plants have a habit of sucking up any carbon dioxide near them with its stoma*, and Henry seems to be right in its range. I would ask Henry how he feels about being "consumed" by a plant, but Henry cant talk.

• A stoma is a specialized hole in a plant, used for gas exchange.

The jarring experience of being sucked into a plant, and placed inside a chloroplast seems to not have fazed Henry. Well, you could see that if we could see him. He is currently in the organelle inside of the chloroplast that contains carbon dioxide, water, and absorbs sunlight. Some of that carbon dioxide is Henry.

The Chloroplast is a section inside a plant cell with the sole purpose of converting carbon dioxide, water, and sunlight for glucose production.

Water, H2O, is a molecule of 2 hydrogen, and one oxygen. It normally takes a water form, but it is important in photosynthesis.

6CO2 + 6H2O + light energy =...

Luckily for us, I got a window installed. Lets observe what the plant is doing with Henry.

It seems the plant is using Photosynthesis to Biosynthesize to Henry into something. This process seems to use water, carbon dioxide, and sunlight as reactants to make a product.

More specifically, six carbon dioxide molecules, and six water molecules.

Biosynthesis is the process of an organism making complex molecules.

Reactants and Products are two sides of are the things reacting, and the things left after the reaction, respectively

Photosynthesis is the process of making glucose using water, carbon dioxide, and sunlight. It is used by Autotrophs.

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

After the mysterious reaction, we discover that it has made glucose and 6 molecules of o2. It may be hard to locate Henry now, but I can assure you he is right at the arrow.

At around this point, Henry realized this plant he was in was making him into food, but the plant was biosynthesizing it itself. If Henry knew what an "Autotroph" was, he would call this plant one right about now.

Glucose is a molecule that is used as a building block of plants, and a part of Cellular Respiration.

An Autotroph is an organism that creates its own food.

After being taken into the plant, and made into glucose, Henry was turned into a part of the plant. Henry, realizing this, now has known he has gone from his seat in the air, to his seat as part of a plants mass. You see, as bricks build a rather sturdy house, glucose builds a rather hardy plant. Not only does Henry feel like part of a house, Henry feels energized. He now has become a organic form of carbon. One with energy within its bonds.

After Henry was part of a plant for many a day, something happened.

After a rather brutal scene that isn't for the faint of heart, or rather the faint of plant? Anyway, this heterotroph has consumed the autotroph, resulting in the death of the plant. After the plants tragic death, Henry realizes only a small amount of energy from the plant transferred to the animal.

Heterotroph means an organism that cannot create its own food.

Death is the ceasing of biological functions in a living being.

As Henry traveled through the creature, he got an unguided tour of the body. You see here one of the creatures cells. If Henry was lucky, he would be transported to one and placed back in the atmosphere, but he isn't the luckiest atom. He happened to just be part of Defecation. Henry is sure he is going to see one of these again, before he goes back to the atmosphere.

Defecation is expelling waste.
