Answer

The second graph shows that something happened that caused the population to decrease. This event could have been anything from an illness that spread throughout the population to some individuals deciding to leave this particular group. Another reason for the decrease could have been environmental factors. The temperature perhaps became too high for organisms, and some died while others could have migrated to another location and group.
