Question

a bird stalks, kills, and then eats an insect. based on its behavior, which ecological terms describe the bird?
a. carnivore, consumer

b. carnivore, autotroph

c. producer, heterotroph

d. herbivore, decomposer

Explanation:

1. Analyze each term:

• Carnivore: Organisms that eat other animals. The bird eats an insect (an animal), so it is a carnivore.
• Consumer: Organisms that cannot make their own food and obtain energy by eating other organisms. The bird eats an insect, so it is a consumer.
• Autotroph: Organisms that make their own food (e.g., plants via photosynthesis). The bird does not make its own food, so it is not an autotroph (eliminates option B).
• Producer: Organisms that make their own food (e.g., plants). The bird does not produce food, so it is not a producer (eliminates option C).
• Herbivore: Organisms that eat plants. The bird eats an insect, not plants, so it is not a herbivore. Decomposer: Organisms that break down dead organic matter. The bird is eating a live insect, not decomposing, so it is not a decomposer (eliminates option D).

1. So the correct terms are carnivore and consumer, which corresponds to option A.

Answer:

A. carnivore, consumer
