This would include heavier elements like iron, magnesium, calcium, and many others from animals falling and sinking, and while some will be caught by fish living in the water, some will get to the bottom. Same thing with some chemicals, for example, quartz is a necessary component to some plants, as their photosynthetic organelles evolved from kinetosynthetic organelles, and integrate the quartz previously required for kinetosynthesis into photosynthesis. | |
