Quiz 2 Flashcards
competition
interaction between two organisms or species that harms both in the process
- intra (within species)
- inter (between species)
- reduces the growth of both organism
competitive exclusion principle
two species cannot live in the place at the same time if they are limited by one or more of the same limiting resources
theory of limiting similarity
two species that are too similar cannot coexist
resource partitioning
inferior species may switch to another resource if there is competition in one community
temporal and spatial patchiness
the best competitor may not always find the best resource or the inferior competitor could find it first
variance
how much individuals differ from the mean
t score
a value that reflects how different two means are
- influenced by standard deviation and sample size
p value
the probability that two means could be drawn from the same population or be not that different
- influenced by t score and sample size
- low score means that the difference is a true difference
what is the evidence of mutualism or competition
competition was portrayed through the decrease in growth when put in the same pot as another organism compared to the growth when in a pot alone
predation vs competition
predation is a relationship in which one organism in the relationship benefits and the other suffers while in competition both organisms in the relationship suffers
how does an antibiotic just kill the bacteria and not human cells
