The student will investigate and understand that interactions exist among members of a population. Key concepts include
a) competition, cooperation, social hierarchy, territorial imperative; and
b) influence of behavior on a population.
Key Knowledge / Concepts
members of a population interact with each other. These interactions include
competing with each other for basic resources,
mates, and territory and cooperating with each
other to meet basic needs.
The establishment of a social order in a population may insure that labor and resources are adequately shared.
establishment of a territory ensures that
members of a population have adequate habitat to provide for basic
Individual behaviors and group behaviors can influence a population.

|| determine the relationship between a populations position in a food web and the types of interactions seen among the individuals of the population.|
The student will investigate and understand interactions among populations in a biological community. Key concepts include
a) the relationships among producers, consumers, and decomposers in food webs;
b) the relationship between predators and prey;
c) competition and cooperation;
d) symbiotic relationships; and
Overview / Key Concepts
| In a
community, populations interact with other populations by
exhibiting a variety of behaviors that aid in the survival
Organisms or populations that rely on each other for basic needs form interdependent communities.
Energy resources of a community are shared through the interactions of producers, consumers, and decomposers.
The interaction between a consumer that hunts for another consumer for food is the predator-prey relationship.
Populations of one species may compete with populations of other species for resources.
| Populations of one species may also
cooperate with populations of other species for
A symbiotic relationship may exist between two or more organisms of different species when they live and work together.
Symbiotic relationships include mutualism (in which both organisms benefit), commensalism (in which one organism benefits and the other is unaffected), and parasitism (in which one organism benefits and the other is harmed).
Each organism fills a specific role or niche in its community.
