The correct order is -

a. 5 > 3 > 4 > 1 > 2 .

Explanation:

In sedimentary rocks, the bottom layer of the rock form initial and the fossils found in them would be older and the layer on top deposited the latest so the fossils found in the top layer would be the youngest.

Newer layers form or deposited on the layers of the oldest or bottom layer of the sedimentary rocks. Hence, the fossils present in the bottom layer would be the oldest fossil and newer fossils will be above them and the youngest would be top.

Thus, the correct answer is - a. 5 > 3 > 4 > 1 > 2 .

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
