Final answer:
The incorrect statement about moose ticks is that they do not harm moose; they are harmful parasites and can cause significant health issues.
Step-by-step explanation:
The statement regarding moose ticks that is NOT true is that 'They do not cause any harm to moose' (Option 3). Moose ticks, also known as winter ticks (Dermacentor albipictus), are ectoparasites that can inflict serious harm on moose populations. Large infestations can lead to anemia, hair loss, and weakened moose, making them more susceptible to predation and environmental stress. Furthermore, severe infestations may result in mortality due to blood loss and secondary infections. These ticks are a concerning factor in moose ecology, and understanding their impact is crucial for wildlife conservation efforts, especially in regions where moose populations are affected by these parasites.
