A. Predator, carnivore, consumer.
B. Predator, autotroph, herbivore.
C. Producer, herbivore, decomposer.
D. Producer, carnivore, heterotroph.
Because the scorpion stalks, kills and eats its food, it is a predator. Because it eats a spider it is a carnivore. Because it ingests food it is a consumer. A producer is an autotroph which is an organism that makes its own food from inorganic substances. A decomposer breaks down dead matter and a herbivore eats only plants.
