Question

The flea population increases because the relationship is mutually beneficial

The flea population increases because there are more dogs to live on

The flea population decreases because the fleas harm the dogs they live on

Answer 1

The correct answer is: The flea population increases because there are more dogs to live on.

When a new dog is brought into a home that already has fleas, the fleas have more hosts available to feed on, which can lead to an increase in the flea population. Fleas rely on host animals for their survival, reproduction, and food source, so having additional dogs provides more opportunities for them to thrive and reproduce.
