Answer: The image complements and exemplifies the content of the text.
Step-by-step explanation
In texts, images are used with different purposes such as summarizing information previously presented, explaining complex concepts, presenting new information, complementing the content of the text, or providing an example. In the case presented, the image most likely complements and exemplifies the content of the text. This is because the image helps the reader to understand the way specific body part such as a long neck helps an animal to get food (complement), and it gives a real example of the concept explained in the text (exemplify).
