Two species have a relationship with one another in an ecosystem. Suppose one of these two species goes extinct. Which type of relationship did the two have if the surviving species population increases after the other goes extinct?

Commensalism

Explanation:

Commensalism - relationship in which one organism benefits while the other is neither helped nor harmed.

Because there were two species we can see that there was not a harmful (parasitism) relationship, nor Mutualism because when one species died the other remained safe.

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
