Question

In recent years, scientists have collected data on populations of Adelie and Gentoo penguins. Adelie penguins are ice dependent. They rely on sea ice as a foraging platform for feeding on prey such a krill and fish, while Gentoo penguins are considered ice-intolerant. How does the data in the graph support or refute the theory of global climate change?

a. The graph refutes this theory, as it shows increases in Adelie and Gentoo penguins.

b. The graph supports this theory, as it shows that penguin populations are fluctuating in number.

c. The graph supports this theory, as it shows a gradual decline in populations of Adelie penguins.

d. The graph refutes this theory, because it does not provide any information on global temperatures.

Answer 1

C. The graph supports this theory, as it shows a gradual decline in populations of Adelie penguins.

Step-by-step explanation:

Since Adelie penguins depend on ice to survive, a decline of ice would spell chaos for their survival. And coupled with the fact global warming means a bigger fluctuation of temperatures and a faster melting of ice on Earth, that would line up with the data of the decreasing Adelie penguins.
