How are the Arctic and Antarctic ecosystems of the tundra similar? How are they different? (please make sure the answer is informatinal and a long answer, thanks!)

They share both similarities. The Arctic and the Antarctic are the two farthest points from the equator and two of the coldest places on earth. Both rotate in and out of darkness throughout the year and have diversity in wildlife.
