Ch 11 Species Inter
| Question | Answer |
|---|---|
| Adaptation | process by which an organism becomes well suited to the demands placed on it by its environment |
| Environment includes not only Abiotic (def) but also ... and (def) | Abiotic factors are temperature, rain fall, pH, etc but also biotic factors, other organisms living in the area |
| Symbiosis results in ... and is... | symbionts; where species live together in close association, such as in commensalism, parasitism, or mutualism. |
| Neutralism (def) | neither species affects the other |
| Amensalition (def) | ONe species is inhibited but the other is not affected |
| Competition (def) | Inhibition of each species by the other; most common type of species interactions in nature |
| Predation (def) | one species benefited; the other inhibited; most common type of species interactions in nature and parasitism is a special case of predation |
| Parasitism (def) | parasitism is a special case of predation; one species benefited the other is inhibited |
| Commensalism (def) | one species benefited; the other not affected |
| Mutualism (def) | benefit of each species by each other |
| Interactions between species are not necessarily... | permanent or unchangeable and can evolve as the environment changes or the animal grows. Over evolutionary time, negative interactions tend to be minimized in favor of positive interactions that benefit the interacting species. |
| When adaptions in one species lead to counter-adaption in the second species and these counter-adaptions, in turn, act as a selective force on the first species, the process is called.... | coevolution |
| Neutralism | neither has anything to do with the other |
| Amensalism | One species come off bad but the other is ignorant; rare because negative actions are minimized over time |
| Competition | Fighting for the same thing. There are two types: interference competition and exploitative competition. |
| Interference competition | involves two species that directly affect one another; physical fight |
| Exploitative competition | involves two species that affect one another without directly interacting; when you have to share batteries between two remotes (relaying on the same food source) |
| Competitive Exclusion | where competition between two species drives the other extict |
| Character displacement | Evolutionary change to avoid competition or minimize the affects |
| Allelopathy | producing toxic chemicals so that trees don't grow near it |
| Predation | eating the other one; consuming of one species by another. Includes herbivory and carnivore. |
| Parasitism | special case of predation characterized by two distinguishing features: tendency of the parasite to obtain nutrition from a host through close association with it rather than killing it, and the size difference between the host and parasite is large. |
| Commensalsim | one species benefits but the other shows no notice. Hard to determine. |
| Epiphytes | are plants that grow on other plants, epiphyte benefit by using their hosts as a place to live but do not affect their hosts in any way. |
| Mutualism | is interaction in which two species benefit from each other. May be either facultative or obligate |
| Facultative mutualism is | although both species benefit from the mutualistic association, each species is capable of surviving without the other. |
| Obligate mutualism is | when the animals can't live without each other, they evolved so their survival depends on the interaction. Its less common |
