1.1
The student describes and explains one of the following: increase in grasses (because mice consume grasses),
decrease in snakes (because snakes consume mice), decrease in rabbits (because hawks would prey upon more
rabbits in the absence of mice as a food source), decrease in lizards (because hawks would prey upon more lizards
in the absence of mice as a food source), decrease in hawks (because hawks consume mice as a food source), or
increase in grasshoppers (because grasshoppers compete with mice for the grasses as a food source).
