Grade Discipline Core Idea
6-8 LS2.A: Interdependent relationships in ecosystems Organisms and populations are dependent on their environmental interactions both with other living things and with nonliving factors, any of which can limit their growth. Competitive, predatory, and mutually beneficial interactions vary across ecosystems but the patterns are shared.
9-12 LS2.A: Interdependent relationships in ecosystems Ecosystems have carrying capacities resulting from biotic and abiotic factors. The fundamental tension between resource availability and organism populations affects the abundance of species in any given ecosystem.
6-8 LS2.C: Ecosystem dynamics, functioning, and resilience N/A
9-12 LS2.C: Ecosystem dynamics, functioning, and resilience If a biological or physical disturbance to an ecosystem occurs, including one induced by human activity, the ecosystem may return to its more or less original state or become a very different ecosystem, depending on the complex set of interactions within the ecosystem.
