What key factor limits the moose population in relation to temperature?

1. Moose inability to sweat in high temperatures

2. Moose need for excessive rainfall

3. Moose preference for cold climates

4. Moose dependence on high humidity

The correct answer is: Moose inability to sweat in high temperatures

The key factor that limits the moose population in relation to temperature is the moose's inability to sweat in high temperatures. Moose are adapted to colder environments, where their thick fur helps insulate them against the cold. However, when temperatures rise significantly, they cannot effectively regulate their body temperature through sweating, which can lead to overheating. This physiological limitation makes it challenging for moose to thrive in warmer climates, as they may struggle to find suitable cool environments that meet their temperature requirements for survival. While moose do prefer cold climates, their inability to cope with heat is a more direct impact on their population dynamics in changing environmental conditions. Additionally, moose do not specifically depend on high humidity or excessive rainfall, as their habitat needs are more closely related to the availability of food resources and suitable temperatures. Taking all of this into account, the inability to sweat in high temperatures stands out as a crucial factor affecting their population.
