Explanation:
Limestone is a kind of sedimentary rock that is rich in minerals, most of them work as nutrients for some living things like corals and clams, that is the reason why in the first point is quite common to find these living things.
In the case of the shale, is a kind of rock that is like compact sand, doesn`t have enough minerals to living things. even more, there are different colors depending the mineral that is the dominant in the rock.
