✔✔F (oxygen) - ✔✔True or False: When plants photosynthesize, they release carbon
dioxide into the atmosphere.
✔✔biota pool - ✔✔When plants photosynthesize, they add carbon to the ___________.
✔✔carbon dioxide - ✔✔When plants die, they are consumed by detritivores and
decomposers that release ________ into the atmosphere and store some carbon in the
soil.
✔✔carnivores, secondary - ✔✔Compare a terrestrial food chain (plants → caterpillars
→ robins → cats) to an aquatic food chain (algae → mosquito larva → catfish → bald
eagles.
Both the robin and the catfish are ________ and ____________ consumers.
✔✔the sun - ✔✔The ultimate source of energy for a terrestrial ecosystem is
_____________.
✔✔autotrophs - ✔✔The sun's energy is converted into chemical energy by
______________.
✔✔0.20 (birth-death/total population) - ✔✔Assume the K-State campus is home to a
population of 100 squirrels. Each year, 30 baby squirrels are born and 10 squirrels die.
What is the per capita growth rate (r) of this squirrel population?
✔✔primary producers - ✔✔In the "Nutrient Pollution" simulation, you learned that algae
and cyanobacteria were the ______________.
✔✔primary consumers - ✔✔In the "Nutrient Pollution" simulation, you learned that
daphnia and bosmina were the ____________.
, ✔✔phosphorus - ✔✔In the "Nutrient Pollution" simulation, you learned that the lake was
limited in the nutrient ___________.

✔✔grasses - ✔✔The dominant plants found in the prairie biome are ________.
✔✔T - ✔✔True or false: Community Structure is influenced by interspecific and
infraspecific relationships.
✔✔abiotic - ✔✔Community Structure is influenced by _____ factors such as climate.
✔✔resource - ✔✔Community Structure is influenced by __________ availability.
✔✔population growth - ✔✔Community Structure is influenced by patterns of
_______________.
✔✔Ecosystem - ✔✔A network of interactions that involves the cycling of nutrients and
flow of energy between a community and its physical environment.
✔✔dependent - ✔✔Is a disease that can kill many individuals in a population density-
dependent or independent?
✔✔dependent - ✔✔Is competition for food among individuals in a population density-
dependent or independent?
✔✔independent - ✔✔Is a flood that kills a large portion of a population density-
dependent or independent?
✔✔dependent - ✔✔Is predation on a population density-dependent or independent?
✔✔dependent - ✔✔Is competition for nesting sites among a population density-
dependent or independent?
✔✔nitrogen - ✔✔An ecologist divided a clear lake in two portions. In part Am he added
phosphorus fertilizer. In part B, he added nitrogen fertilizer. Two months later he found
part A remained clear but part B had an abundance of algae. Based on this experiment,
the scientist can draw the conclusion that the original lake was limited by a ________
nutrient and the addition of the ________ nutrient may lead to eutrophication.
✔✔population - ✔✔All the human inhabitants of Manhattan, KS is an example of a
___________.
