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.
true,Coevolution the hypothesis that when the virus
and the host reciprocally affect each other's
evolution
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 we call a_______, Depending on their role as
producers or consumers, species or groups of
species can be assigned to various trophic levels.
trophic level
Ultimately, the length of a food chain depends on
the___________between trophic levels.
efficiency of energy transfer
a diagram the nonlinear ways that matter and
energy flow through a community.
food web
A keystone species ___________________________.
strongly affects the structure of a community
Which of the following scenarios describes an
indirect effect?
the abundance of plants increases when predators
limit herbivores.
