Carbonized fossils are made of:
ExtremeBDS [4]
Carbonized remains are thin, approximately two-dimensional films of carbon preserved on a flat surface of rock. They are most often black in color, reflecting the fact that they composed mostly of carbon (as is coal, which is also black in color). Most fossils that exhibit “soft part” preservation are carbonizations.

I would say the answer is the Carbon remains of the original organism.

What prevents the full intake of calcium in milk?
katrin [286]

Phosphorous: Also known as phosphoric acid and phosphate, phosphorous, which is in cola and many processed foods, can interfere with calcium absorption.

Insoluble fiber: This type of fiber, such as the kind in wheat bran, reduces calcium absorption

Foods with high levels of oxalic acid include spinach, collard greens, sweet potatoes, rhubarb, and beans and this will interfere with calcium absorption.

  • Earthquake etc.

Therefore, III only (floods and drought) is an example of density-independent factor affecting population growth.
