SC Standards Standard 7.EC.5: The student will demonstrate an understanding of how organisms interact
with and respond to the biotic and abiotic components of their environments. 7.EC.5A Conceptual Understanding: In all ecosystems, organisms and populations of
organisms depend on their environmental interactions with other living things (biotic factors) and with physical (abiotic) factors (such as light, temperature, water, or soil quality). Disruptions to any component of an ecosystem can lead to shifts in its diversity and abundance of populations.
7.EC.5A.1: Develop and use models to describe the characteristics of the levels of organization within ecosystems (including species, populations, communities, ecosystems, and biomes).
S.1A.2: Develop and use models to (1) understand or represent phenomena, processes, and relationships, (2) test devices or solutions, or (3) communicate ideas to others.
SC ObjectivesEssential Learning Experiences: It is essential that students develop and use models to describe the characteristics of the levels of organization within ecosystems.

SC Standards Standard 7.EC.5: The student will demonstrate an understanding of how organisms interact
with and respond to the biotic and abiotic components of their environments. 7.EC.5B Conceptual Understanding: Organisms in all ecosystems interact with and depend
upon each other. Organisms with similar needs compete for limited resources. Food webs and energy pyramids are models that demonstrate how energy is transferred within an ecosystem.
7.EC.5B.1: Develop and use models to explain how organisms interact in a competitive or mutually beneficial relationship for food, shelter, or space (including competition, mutualism, commensalism, parasitism, and predator-prey relationships).
S.1A.2: Develop and use models to (1) understand or represent phenomena, processes, and relationships, (2) test devices or solutions, or (3) communicate ideas to others.

________________________________________ to both the parasite and the host
populations.

__________________________________________________________________ and
spread.
Mutualism ___________________________________________________________________________
___________________________________________________________________________
Because the two organisms ____________________________________________________
___________________________________________________________________________ .
o For example, bacteria, which have the ability to digest wood, live within the digestive tracts of termites; plant roots provide food for fungi that break down nutrients the plant needs.
Commensalism ___________________________________________________________________________
___________________________________________________________________________ .
o For example, barnacles that attach to whales are dispersed to different environments where they can obtain food and reproduce; burdock seeds that attach to organisms and are carried to locations where they can germinate.
