In recent years, scientists have collected data on populations of adélie and gentoo penguins. adélie 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? graph shows the adele penguin population size decreasing over time from 8,000 in 1975 to 2000 in 2005. the gentoo penguin population size ranges from 2500 to 4000 in 2005. © 2016, noaa the graph refutes this theory, as it shows increases in adélie and gentoo penguins. the graph supports this theory, as it shows that penguin populations are fluctuating in number. the graph supports this theory, as it shows a gradual decline in populations of adélie penguins. the graph refutes this theory, because it does not provide any information on global temperatures.
