Dogs conditioned to salivate to stimulation of the thigh also begin to salivate when stimulated on other body parts. this best illustrates

generalization

Explanation:

In generalization conditioning, though the stimuli is different but it has some similarity in its nature which causes similar kind of responses.

Like in this case when dog is condition to salivate when it is stimulated on thighs but since this conditioning transforms into generalized conditioning the dog even salivates when it is stimulated on some other body parts.  

Hence, the correct answer is generalization

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)
