KSU BIOLOGY 198 UPDATED 2026 EXAM SCRIPT
QUESTIONS AND ANSWERS GRADED A+
✔✔Per Capita growth rate - ✔✔=b-d
how many individuals are added to the population per individual already living.
✔✔exponential - ✔✔G=rN is the equation for __________ growth
✔✔Carrying Capacity - ✔✔_________ limits the population growth. Logistic growth hits
carrying capacity and the population levels off.
✔✔Logistic Curve - ✔✔A ___________ describes the growth of a population when the
effects of the carrying capacity can be seen. something is limiting the population size,
the amount of NPP available.
G=rN(K-N/K)
When it reaches carrying capacity, no more growth occurs.
✔✔Density-dependent - ✔✔Examples of this kind of factor includes biological,
predation, inter and intra specific competition, accumulation of waste.
✔✔Density-independent - ✔✔Density-________ factors influence morality in a
population regardless of population density. These are physical or chemical (abiotic
factors) such as natural disasters.
✔✔1 - ✔✔High death rate in older organisms is a Type ___ Survivorship.
✔✔2 - ✔✔High death rate in all ages of organisms is a Type ___ Survivorship.
✔✔3 - ✔✔High death rate in younger organisms is a Type ___ Survivorship.
✔✔Interspecific - ✔✔A ___________ interaction is between different species.
✔✔intraspecific - ✔✔A ___________ interaction is between the same species. It helps
with population growth because it can cause reproduction but also competition.
✔✔Abiotic - ✔✔___________ factors are non-living influences on the organisms and
their environment (i.e. temperature, ph, sunlight)
✔✔adaptive traits - ✔✔competition evolves, helps maximize an organisms reproductive
success
✔✔patterns of population growth - ✔✔exponential: no carrying capacity, J shaped.
logistic: has hit carrying capacity so population does not grow anymore. S shaped.
, ✔✔Niche - ✔✔A specific area where an organism inhabits the role or function of an
organism.
✔✔Coevolution - ✔✔________ is when genetic change in one species causes a
subsequent change in the genetic structure of another species.
✔✔Primary succession - ✔✔occurs when new land is formed. the community structure
would have to start for the beginning and learn how to grow and survive.
✔✔Secondary succession - ✔✔distributed and remains of the previous community. the
nutrients are still left but they have to start again
✔✔Nutrient enhancement - ✔✔directly affects the producer community in the most
situations. it would increase the growth rate or pop size of the producer. not always!
decrease in oxygen levels, which affect all the consumer trophic levels.
✔✔community structure - ✔✔everything effects everything, if NPP goes down the
population will go down. etc.
✔✔aquatic - ✔✔________ ecosystems are more fragile than others. Plants and
bacteria get to nitrogen, and a limiting factor is phosphorus.
✔✔nutrients - ✔✔Increased ________ will have consequences on the flow of energy
and the cycling of nutrients in a community. Energy levels increase in the producer
populations and some of the energy is passed on.
✔✔Biological magnification - ✔✔________ refers to the effects of increasing toxic
concentration on a food chain.
The higher the trophic level, the more toxins due to the amount they consume and the
little amount they are able to secrete.
✔✔Biological magnification - ✔✔______________ has serious consequences on
people's health (e.g. mercury poisoning).
✔✔Qualitative - ✔✔________ data characterizes, but doesn't measure.
✔✔Quantitative - ✔✔A type of data that is quantified, clarified, and is amenable to
statistical manipulation.
✔✔Autotrophic primary producer - ✔✔Helianthus annuus, also known as the common
sunflower, is grown as a food source for humans, birds, and livestock. Classify this
organism as:
autotrophic/heterotrophic
primary/secondary
