Construct an explanation to predict the type of symbiotic relationship that exists between the hippo and oxpecker birds?
Allisa [31]
<h2>Answer:</h2>

However, the bird gets food by making little cuts in the hippopotamus to obtain insects. This isn't entirely harmful to the hippopotamus though.</u></em></h2>
