7th Grade (SCI) Life Science Standards [LS2] Ecosystems: Interactions, Energy, and Dynamics
SCI-MS.LS2.05 Evaluate competing design solutions for maintaining biodiversity and
Clarification Statement: Examples of ecosystem services could include water purification, nutrient recycling, and prevention
of soil erosion. Examples of design solution constraints could include scientific, economic, and social
considerations. Disciplinary Core Ideas LS2.C: Ecosystem Dynamics, Functioning, and
Biodiversity describes the variety of species found in
Earth’s terrestrial and oceanic ecosystems. The
completeness or integrity of an ecosystem’s
biodiversity is often used as a measure of its health.
LS4.D: Biodiversity and Humans
Changes in biodiversity can influence humans’
resources, such as food, energy, and medicines, as
well as ecosystem services that humans rely on—for
example, water purification and recycling
