Question

Rough-skinned newts and common garter snakes are in an "evolutionary arms race." In this phenomenon, two species continually evolve adaptations against one another to increase their own chance of survival. Rough-skinned newts produce tetrodotoxin, a type of poison, as a defense mechanism. Most common garter snakes have some resistance to the toxin. In areas where common garter snakes and rough-skinned newts coexist, rough-skinned newts express very high levels of tetrodotoxin, and common garter snakes have evolved a very high degree of resistance to tetrodotoxin. Based on this information, what is the most likely relationship between common garter snakes and rough-skinned newts?

A.
obligate parasitism
B.
predator and prey
C.
facultative mutualism
D.
commensalism

Answer 1

I got it correct!!!!!!!

B. Predator and prey

Answer 2

The correct answer would be B. predator and prey.

Predator and prey is a type of natural relationship in which one organism kills and consume the other organism.

For example, a lion is a predator which kills and consume deer (prey).

During the course of evolution, prey evolves various adaptations to overcome predation and increases its survival rate.

In addition, a predator also evolves to increase its success rate in predation.

Similarly, rough-skinned newts (prey) evolve to produce poison as a defense mechanism and greater snakes (predator) evolve resistance against that poison to increase its survival rates.
