Answer:
The correct answer is "invasive species".
Step-by-step explanation:
If the fire is used safely it can restore native grasslands and provide many benefits to nature. After a fire, some animals are attracted to the lush re-growth of grass and concentrate their grazing in that burned area. Fire in combination with cattle is used to control trees, and invasive species and keep grasslands healthy. If controlled fire is applied regularly it can reduce the intensity of an unplanned fire.
