1. Unit at a Glance
This unit scales from individual organisms to entire ecosystems, building a layered understanding of how ecological systems function. We start with how individual organisms respond to their environment, then move up to population dynamics, community interactions, ecosystem energy flow, and end with an analysis of how disruptions impact biodiversity.
Common Pitfalls
Why: This mix-up leads to incorrect calculations for both exponential and logistic growth problems.
Why: Most energy is lost to the environment as heat during cellular processes.
Why: Many natural disruptions are critical for ecosystem renewal and maintaining native biodiversity.
