the pictures show one of earths polar ice caps in 1984 and 2012. what change in the arctic ecosystem is being show in the pictures?
a decrease in the size of the ice cap because earths climate is changing.
a decrease in carbon dioxide being absorbed causing the ice cap to increase.
an increase in temperature at the earths core causing the ice cap to melt.
an increase in the amount of ice in the ice cap because succession is occurring.

Explanation:

The pictures compare polar ice caps in 1984 and 2012, showing a visible reduction in the white (ice) area. This aligns with the effect of Earth's changing climate leading to ice cap shrinkage. Other options are incorrect: B claims ice increase (opposite of observation), C attributes melting to core temperature (unrelated to surface ice), D claims ice increase via succession (incorrect and irrelevant).

Answer:

A. A decrease in the size of the ice cap because Earth's climate is changing.
