What is a Problem with an Obligatory Mutualistic Interaction Between

Question

What is a problem with an obligatory mutualistic interaction between two species?
A) If one species becomes extinct, then so must the other
B) If one species evolves, then the other might have to evolve to adjust to the first species
C) If one is vulnerable to a predator, then so might the other be
D) All of the above

Accepted Answer

Obligatory mutualistic interactions mean that both species are highly dependent on each other for survival. If one species faces extinction, the other is likely to follow due to the loss of the benefits provided by the extinct species. Similarly, evolutionary changes in one species can necessitate adaptations in the other to maintain the mutualistic relationship. Additionally, if one species is vulnerable to a predator, the other might also be at risk, either directly through shared vulnerabilities or indirectly through the loss of its mutualistic partner.
