AP Biology Unit 8: Ecology — Mind Map

Covers population ecology (exponential vs. logistic growth, carrying capacity, r/K selection, survivorship curves), community interactions (competition, predation, symbiosis, keystone species), ecosystem energy flow and the 10% rule, biogeochemical cycles, and human impacts on ecosystems.
