7th Grade (SCI) Life Science Standards [LS2] Ecosystems: Interactions, Energy, and Dynamics
SCI-MS.LS2.02 Construct an explanation that predicts patterns of interactions among
organisms across multiple ecosystems.
Clarification Statement: Emphasis is on predicting consistent patterns of interactions in different ecosystems in terms of the
relationships among and between organisms and abiotic components of ecosystems. Examples of types of
interactions could include competitive, predatory, and mutually beneficial. Disciplinary Core Ideas LS2.A: Interdependent Relationships in
Similarly, predatory interactions may reduce
the number of organisms or eliminate whole
populations of organisms. Mutually beneficial
interactions, in contrast, may become so
interdependent that each organism requires
the other for survival. Although the species
involved in these competitive, predatory, and
mutually beneficial interactions vary across
ecosystems, the patterns of interactions of
organisms with their environments, both living
and nonliving, are shared.
Student Learning Targets:
I can recognize or recall specific terminology (predator/prey, producer/consumer, symbiotic relationships, biotic and abiotic factors, habitat and niche, competition, levels of organization in the ecosystem: species, population, community, ecosystem).
I can identify symbiotic relationships.
I can predict what would happen to an ecosystem with changing ratios of producers, consumers, or decomposers.
I can compare and contrast habitat and niche.
I can differentiate symbiotic relationships.
