What is the primary consequence of ticks infesting moose?

1. Increased food availability for moose

2. Better resistance to cold weather

3. Weakness and exhaustion leading to death

4. Improved growth rates in juvenile moose

The correct answer is: Weakness and exhaustion leading to death

The primary consequence of ticks infesting moose is weakness and exhaustion leading to death. When ticks attach to moose, they feed on the animal's blood, which can result in significant blood loss. This blood loss weakens the moose, making it difficult for them to find food and maintain their energy levels throughout harsh conditions, particularly in winter when food sources are already limited. Additionally, a heavy tick infestation can cause stress and result in various health complications, ultimately contributing to decreased survival rates. The combined effects of anemia from blood loss, weakened immune responses, and increased susceptibility to disease can culminate in severe health issues or fatal outcomes for the moose. Understanding the impact of tick infestations is crucial for managing moose populations and their health in ecosystems where these ectoparasites are prevalent.
