Standard 1: Ecology
Major Objectives IS Suggested Activities Suggested Assessments
Concept A: Ecological Relationships
Explain the nature of interactions between organisms in
different symbiotic relationships (mutualism: E. coli in colon)
(commensalism: Spanish moss (epiphyte) in trees) (parasitism:
mosquito on mammal). (4.1.A.a)
Concept B: Ecological Relationships
Explain how cooperative (symbiotic) and competitive
(predator/prey) relationships help maintain balance within an
ecosystem. (4.1.A.b)
Students will be given various symbiotic
relationships and identify each relationship
as mutualism, commensalism, or parasitism.
(1.5, 1.8, 4.1, SC3)
Students will be presented with graphs that
explain how cooperative and competitive
relationships help maintain balance in the
ecosystem.
OR
Students will view video clips that recognize
the importance of cooperative and
competitive relationships in the ecosystem.
Students will complete a relationship
chart to identify and group symbiotic
relationships.
Students will analyze graphs to
explain how cooperative and
competitive relationships help
maintain balance in the ecosystem.
Concept C: Ecological Relationships
Explain why no two species occupy the same niche in a
community. (4.1.A.c; 7.1.B/C/E)
Concept A: Energy Flow in Ecosystems
Illustrate and describe the flow of energy within a food web
(food chain, autotroph, heterotroph, scavenger, decomposer).
(4.2.A.a)
Concept B: Energy Flow in Ecosytems
Explain why there are generally more producers than
consumers in an energy pyramid (pyramids of energy, biomass,
and numbers; trophic levels) (4.2.A.b; 7.1.B/C/D)
(1.6, 3.5, 4.1, SC3, SC4)
Students will observe the niches’ of
organisms in a rotting log.
OR
Students will discuss the niches of various
herbivores in the Serengetti Plain.
(1.3, 1.6, 3.5, SC3, SC4)
Students will choose a biome and design a
food web with a minimum of 10 organisms
from the biome.
(1.6, 1.8, 3.5, SC3, SC4)
Given a set of data, students will calculate
the biomass of each trophic level and assign
the results to a ecological pyramid.
(1.5, 1.6, 1.8, 3.5, SC3, SC4)
Students will be asked to discuss four
organisms and their niche that they
observed in the rotting log.
Given a food web, categorize each
organism using appropriate
vocabulary.
Design an ecological pyramid and
calculate the total numbers and
biomass for each trophic level.
