Scientists study bubbles trapped in ancient glacial ice todetermine how concentrations of nitrogen and carbondioxide gas have changed over time. However, bubblesin glacial ice cannot provide information about changesin phosphorus. Explain why air samples are not usefulfor this purpose, and propose an alternative method tostudy how the amount of phosphorus in a region haschanged over time.

Paleontology

A branch of science concerning the scientific study of life from ancient times is known as paleontology. The scientists working on paleontology are known as paleontologists. Paleontologists collect the fossils of organisms from ancient times to classify them. The paleontologists also study the environment from ancient times to study the interactions between different organisms.
