Abird stalks, kills, and then eats an insect. based on its behavior, which pair of ecological terms describes the bird?
herbivore, decomposer
producer, heterotroph
carnivore, consumer
autotroph, herbivore

For the answer to the question above, A carnivore is an animal that gets food from killing and eating other animals. Carnivores generally eat herbivores, but can eat omnivores, and occasionally other carnivores. So my answer would be the third choice. Carnivore, Consumer.
