Answer:
The tundra ecosystem is one of the coldest ecosystem on the earth, which has few trees, high winds, much snow, and low rainfall. Some of the species found in that environment are arctic foxes, caribou, and polar bears.
Global warming has negatively impacted the tundra ecosystem as it is melting ice, which results in increased water level and changing the weather pattern. It means there are more green spaces, which provide more space for population growth. But it also harms the tundra ecosystem, as some of the species become the prey and it negatively impacts the ecosystem.
