The making of replicas of the original fossils, is pretty much the say way, just different materials, in which the fossils originally have been formed and preserved.
When an organism dies, be it a plant or an animal, it gets fossilized only if very quickly after the death it is covered with sediments or mud. The sediments or the mud protect the plant or animal from the outside influences, so once it is kind of in a vacuum, or protective layer if you will, in which parts of the plant or animal that are long-lasting are preserved.
The clay and plaster used for the replica, work in the same way, because they wrap around the fossil tightly and isolate it from outside influences, with the result being different though, as they just make a copy of the fossil.

Answer:
b. making an observation and asking a question 
Explanation:
In scientific method there need to be a situation to be study. In this description, the scientist first observed that in a certain region there is some kind of trees and the other variable is the great amount of deer. 
After making different observations, and some research of other areas similar to the one that is study, she is asking what is the relation among the animals and the trees.

 worms get their energy through the biological process of cellular respiration where glucose from the food they eat is converted into ATP. This molecule is packed with potential energy, and is used by the cells within the worm to do work.
Hope this helps (:
