Which of the following observations most strongly supports the hypothesis that ants and Acacia trees
have experienced one-on-one coevolution?
The removal of either trees or ants from the environment causes the extinction of the remaining
species.
T/F: Coevolution has important consequences for medicine because pathogens coevolve with their
hosts.
true
How can several species of dung beetles coexist?
There has to be something about their niches that differ; if they both eat dung, it can't be what they eat,
but there has to be something else that keeps them from out-competing one another; there has
to be some other resource that's limiting the one species from getting all the dung.
True or False? If species of beetles have the same niche, eventually all but one species will become
extinct.
true
True or False? If species compete for many generations, natural selection would cause their niches to
diverge.
true
,T/F: While spreading through the human population, the viral population experiences one-on-one
coevolution with the population of humans.
false
T/F:When humans and viruses interact as host and pathogen, respectively, an evolutionary change in
one population will result in selective pressure on the other population.
true
T/F: Viruses can become less harmful to humans through natural selection in the human population or
natural selection in the viral population.
true
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.
false
T/F: The deadliest viruses for humans are likely to be ones that have spent little time infecting the
human population.
true
is a linear sequence of organisms through which matter and energy pass
food chain
the different types of organisms are organized by their position along the food chain
, trophic levels
All food chains start with this at their base, these organisms transform an inorganic matter and energy
into organic forms.
primary producers
The second tier of a food chain consists of this, and are the first organisms in the chain to eat other
organisms. Since primary consumers eat photosynthetic organisms, such as plants, we can also call them
herbivores.
primary consumer
The remaining tiers of a food chain consist of higher-level consumers, eat primary consumers; and is
carnivores
secondary consumer
eat secondary consumers. In most cases, these consumers are animals that eat other animals, so we can
also call them carnivores. Because animal tissues are far easier to digest, a greater fraction of matter
and energy passes between these levels of a food chain.
tertiary consumers
Matter and energy pass in a single direction along a food chain, starting with the primary producers and
ending with the highest level of consumers. Each organism in a food chain occupies a single tier, which
