Final answer:
The coldest temperatures and shortest growing seasons are found in the Arctic tundra biome.
Step-by-step explanation:
The coldest temperatures and shortest growing seasons are found in the Arctic tundra biome.
The Arctic tundra experiences extremely cold temperatures, with an average winter temperature of -34 °C (-34 °F) and a short growing season of approximately 10–12 weeks.
Due to the low temperatures, plant growth in the Arctic tundra is rapid during the short growing season when there are almost 24 hours of daylight.
