Does kelp sink when it dies?
Kelp sinks only when small sacks of air attached to the plant are broken. If the sacks are broken while it is alive, it will sink and die. If the kelp dies, but the air sacks are not broken, it will float until enough are broken to make the kelp too heavy for the amount of air in the sacks. However if it is dead for a long time, sometimes weeks or months, it will decay enough for the sacks to rupture. The bottom line is that kelp rarely sinks soon after it dies, it will most often end up on shore.
Asked in Blood
How does the blood get oxygen into it?
You breathe. When you breathe, air comes in through your nose. It goes into your lungs. In your lungs are thin small sacks. Air goes on one side, blood on the other. Air filters through the little sacks. The Hemoglobin in your blood gets oxygen from that air that filters through those little sacks in your lungs. Carbon dioxide and a few other gasses are dissolved or carried by your blood stream. They diffuse out through those little sacks. When you breathe out, you get rid of waste gasses, mainly carbon dioxide.
