This AP Biology study guide covers Ecology (Unit 8), focusing on interactions between organisms and their environment, energy flow, biodiversity, and ecosystem change, especially due to disruptions. Key concepts include population dynamics, community structure, species interactions (e.g., mutualism, predation, competition), and the roles of keystone species. It also emphasizes the importance of energy acquisition and transfer within ecosystems, and factors influencing population growth like carrying capacity and density-dependent/independent factors.
