Question

"Over the past few decades, researchers have observed declining numbers in two species of penguins native to the West Antarctic peninsula. New evidence is pointing to a decline in their food supply as the primary cause for the recent drops in their numbers. These penguins feed on krill, small animals that grow and develop under ice masses. The graphs below show data related to two factors: atmospheric carbon dioxide (CO2) levels and Antarctic ice mass. The diagram of a generalized Antarctic food web illustrates the role of the penguins.

State one possible relationship between CO2 levels and the change in Antarctic ice mass"

Answer 1

After reading the information given and studying the graphs you posted above, there are a few different things can can make the relationship between the CO2 levels and the change in the ice mass.

One possible relationship is an increase in CO2 levels caused the ice to melt. A couple of other reasons are; as the level of CO2 increased, the ice mass decreased and an increase in CO2 brought about by global warming , which then melted the ice.
