Concept C: Ecological Relationships
Explain why no two species occupy the same niche in a
community.
Concept A: Energy Flow in Systems
Illustrate and describe the flow of energy within a food web
(food chain, autotroph, heterotroph, scavenger, decomposer).
Concept B: Energy Flow in Systems
Explain why there are generally more producers than
consumers in an energy pyramid (pyramids of energy, biomass,
and numbers; trophic levels)

Students will analyze data involving
the growth rates of paramecia species
cultured separately and together.
(1.5, 1.6, 1.8, 3.5, 4.1, SC4, SC7)
Students will create a food web.
(1.6, SC3, SC4)
Given a set of data, students will
calculate the biomass of each trophic
level and assign the results to an
ecological pyramid.
Students will discuss how an
ecologist would explain the impact
the introduced rabbit population had
on the sheep population in Australia.
Students will analyze a food web and
identify the trophic levels.
Students will identify that when
trophic levels are arranged for an
ecosystem, the shape is pyramidal and
discuss why.
Concept C: Energy Flow in Systems
Given a scenario, predict how energy distribution and energy
use will be altered due to changes in a food web.
Concept A: Cycles
Explain the processes involved and the importance of recycling
nitrogen, oxygen, and carbon through a system.

(1.5, 1.6, 1.8, SC4)
Students will evaluate food webs and
predict what happens when organisms
are removed or introduced to the
ecosystem.
(1.6, 3.5, 4.1, SC3, SC4)
Students will diagram the carbonoxygen
cycle and discuss the
importance of recycling matter.
Students will evaluate the
consequences to the ecosystem when
an species is removed or introduced.
Students will analyze the nitrogen
cycle.
Concept A: Populations
Identify and explain the limiting factors that may affect the
carrying capacity of a population within an ecosystem (logistic
v. exponential growth)(e.g. drought, disease).
Concept A: Populations
Predict how populations within an ecosystem change in number
and/or structure in response to hypothesized changes in biotic
and/or abiotic factors.

(1.6, SC5)
Students will construct graphs
representing logistic and exponential
growth.
(1.6, 1.8, SC4)
Students will evaluate food webs and
predict what happens when organisms
are removed or introduced to the
ecosystem.
Students will identify the parts of the
logistic growth curve.
Students will evaluate the
consequences to the ecosystem when
a species is removed or introduced.
