Double Points!
Newton's First and Third Laws of Motion
An object at rest stay at rest and an object in motion stays in motion until acted upon by an unbalanced force.
For every action there is an equal and opposite reaction

Double Points
explain the difference a carnivorous (carnivore) predator/ prey relationship and a parasitic (parasite) predator/ prey relationship
Parasite attaches to a host and takes nutrients/ blood from its prey, might not die
Carnivore just eats it and kills its prey
