Intro to Biology Questions
1. If an endangered species such as the Santa River Woolly Star were to become extinct, what effects might this have on other species?
The community of organisms will be greatly affected if the Santa River Woolly Star were to become extinct. The Woolly Star is an interwoven strand in a crossing of organisms that are all dependent upon one another for survival. The Woolly Star also stabilizes the sand after flooding which has a [positive effect on other organisms.
2. What do the J- and S- shaped population curves indicate about the life span of an organism?
Organisms that live in a temporary habitat are examples of J shape growth curve. J shape growth curve indicates that the organisms outgrow the amount of resources available and death rates increase. S shaped growth curve organisms are affected by the more organisms in the population the more limiting the environment is to population growth. Population size in S shape double as it does in J shape however as more organisms appear they compete for limited resources in time the population stabilizes at a rate the environment can sustain.
3. Does competitive exclusion limit the diversity within a given community?
Competitive exclusion will eventually limit diversity. As both species compete for a food surface one will typically dominate and the other would become extinct and therefore there would be limited diversity.
4. Why are field studies, such as the monitoring of owls, important in the study of ecology?
The ecology is the study of the community which is a group of organisms including animals and vegetation that tend to occur together. Field studies that monitor owls review the relationship between the environment, predator and prey.
5. How does mutualism differ from commensalism?
Mutualism is an example of when both members/participants benefit from the partnership. In the example given in the video a commensalism relationship may be a hole in a tree and an owl living in it. The owl benefits the
