What are characteristics of bogs?

"Bogs are characterized by spongy peat deposits, acidic waters and a floor covered by a thick carpet of sphagnum moss. Bogs receive all or most of their water from precipitation rather than from runoff, groundwater or streams."

How were bogs formed?

"Once plants began to decompose at the edge of a lake and once conditions were right for peat fen to form, the lakes slowly started to reduce in size. The fen continued to grow and over time a raised bog habitat began to form. The only water that is supplied to a raised bog is rainwater which is very low in nutrients."

C. Developmental biology.
D. Fossil record.

Answers

Answer:

D. Fossil record.

Explanation:

The fossil record evidences the evolutionary history of life on Earth by tracing the life forms that existed from earlier geological times and remained in the sedimentary rock. Different fossils were dated in the sedimentary rocks of all geological periods. The simplest forms of life were discovered in the oldest rocks, while more complex fossil organisms were found in the newest rocks. In consequence, the fossil record can support the evolutionary process as proposed by Charles Darwin, who indicated that the simplest forms of life evolved in more complex organisms.
