Because natural selection is caused so that an organism can adapt and better survive their environment. They are involved in the formation of fossils because organisms that die are buried in sediment and become fossils.

Some species are more likely to perish but, the most healthy frogs will most likely evolve and find something else to eat.
Primary succession is a method of fertilizing soil that was barren and had never supported plant life, for example soil left over by a moved glacier of lava.
The soil is first "normalized", using pioneer species such as lichens, algae and fungi.
After this, plants able to survive in less harsh conditions such as grasses.
Therefore, the fertility of soil during early years of primary succession does not increase much and it is a process that involves a long period of time.
