[Q]: Process:  -The organism must die to begin the process -The soft tissue decomposes -The bones are left behind -Scavengers tear the body apart and move the bones elsewhere -Wind and rain also scatter the bones further -The bones left behind will weather and become buried by sand and soil -The proteins in the bone are replaced with minerals that are dissolved in the soil -This creates a rock-like substance called a fossil -Water and wind erosion wear away the layers of soil on top of the fossil -This makes discovery of the fossil possible.
 Question: What is the effect of animals eat more of the bones on less bones being left behind.?
