The chart shows how well each beetle with each trait were able to survive in their environments, and Mutant 1 was clearly out living the other two, because as you can see mutant 2 has only last for at least one generation, while the non-mutated one lived a little longer. This is because Mutant 1 developed the trait that made its shell darker, and thus it's easier for them to hide from predators, and they were able to successfully pass on their genes to their offspring so now they can do the same.

Trees and birds have a commensalism relationship. The birds benefit from having a place to build their nests, while the trees are unharmed and not impacted by the bird’s presence.
