8) Explain the causes of an evolutionary arms race between consumers and the species that consume. (Ch. 14) 9) If one species provides a habitat as part of a mutualistic relationship, what is the probable effect on the abundance and distribution of the other species? (Ch. 17) 10) Explain how ants and acacia trees fulfill the definition of a mutualistic relationship. (Ch. 17) 11) If cleaner fish consume both parasites and scales from larger fish, what would determine whether the interaction is best categorized as mutualism or parasitism? (Ch. 17) 12) What might prevent a species in a mutualism from reaping the benefits from a partner without providing a benefit in return? (Ch. 17)Explanation / Answer
8) the evolutionary arm race is a kind of evolutionary competition between two species. The main cause of evolutionary arm race between consumer species and the species they consume is "Coevolution". A set of co evolving genes develope adaptation and counter adaptation against each other' both the species (prey and predator) may often show an evolutionary pattern valled "escalation": predators evolve powerful weapons and prey evolve powerful defenses against them.
9) if one provides habitat to a species of a mutualistic relationship the other species will get nutrition from that species. In mutualism both the host and the other species get benefited. So if one is giving habitat to other other that species is getting habitat as well as nutrition from host species.
10) ants and acacia tree both show mutualistic relationship. The acacia tree provides food and accomodation to the ant in the form of food body and nectar as well as hollow thorn which can be used as nests. The ants return this favour by protecting the plant from bacterial growth on plant and herbivorous species also.
11) cleaner fishes consume both the parasites and scales from the larger fishes this kind of interaction is mutualism because cleaner fishes are getting food and nutrition. On the other hand large fishes are enjoying by romoving harmful parasites from their bodies. If small fishes eat tissues of consume mucus from large fishes than only it would have been predation. But in this question it is mutualism.
12) in a mutualism sometimes one species get benifited but it does not give benefit to other species in return. These types of species which gives nothing in return are called cheaters. Cheaters selfishly use common resources to maximize their individual fitness at the expanse of the group.
