BIO 182 EXAM 3 QUESTIONS &
ANSWERS (GRADED A+)
T/F The model of competition between species can ignore competition within
species. - ANSWERF
T/F The larger the competitive effect on a species (alpha or beta), the more likely the
species will persist during competition. - ANSWERF
Humans should not kill, confine, or otherwise interfere with the lives of animals that
have rights. Animal Rights - ANSWERAnimal Rights
T/F If the immune system of humans evolves to reduce the reproduction of viruses,
the viral population would likely experience the natural selection of viruses that are
less harmful to humans. - ANSWERF
T/F The deadliest viruses for humans are likely to be ones that have spent little time
infecting the human population. - ANSWERT
A keystone species ___________________________. - ANSWERA species that
influences the survival of many other species in an ecosystem
T/F An indirect effect must involve at least three species. - ANSWERT
Many places that humans greatly value or enjoy visiting would be off limits if they are
also used by individual non-human animals who may be impacted, hurt, or killed by
human presence. - ANSWERAnimal Rights
Certain species may be considered more important than others or prioritized over
other species. To some extent, in this perspective, the importance of a species to
ecosystem functioning influences how humans 'should' intervene in the environment.
- ANSWERRespect for Nature
Prioritizing individual animals requires radical changes to the ways we currently
interact with animals, across agriculture, pet ownership, conservation, etc. This
would be difficult to implement and have far reaching impacts. - ANSWERAnimal
Rights
T/F When two species have different niches, the competition coefficients (alpha and
beta) are likely to be less than 1.0. - ANSWERT
T/F If two species compete, neither species will reach its carrying capacity before
one of the species goes extinct. - ANSWERT
T/F The rate of population growth (r) determines whether a species can persist
during competition. - ANSWERF
