A bird 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

Carnivore, consumer.

Explanation:

Predators do that, not scavengers or herbivores (or any other category).

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
