What limitation significantly impacts the growth and reproduction season in the Arctic Tundra?

The limitation that significantly impacts the growth and reproduction season in the Arctic Tundra is the short season of growth and reproduction. The Arctic Tundra experiences long periods of extreme cold and darkness during the winter months, leading to a very brief growing season that typically lasts only a few months during the summer. During this time, conditions may be favorable for growth due to the increased temperatures and daylight, but they are often still limited by factors such as soil moisture and nutrient availability.

This short window for growth and reproduction restricts the types of species that can thrive in this biome, as many plants and animals do not have enough time to complete their life cycles before the onset of freezing temperatures and darkness reoccurs. This limitation leads to a unique set of adaptations among organisms, such as the ability to grow quickly and reproduce within that narrow timeframe.
