AP Environmental Science Quiz: Population, Consumption, and Biodiversity

📚 Quick Study Guide

• 📈 Population Dynamics: Population growth is influenced by birth rates (b), death rates (d), immigration (i), and emigration (e). The formula for population change is: $Population Change = (b + i) - (d + e)$
• 🌱 Carrying Capacity (K): The maximum population size of a species that the environment can sustain indefinitely, given the available resources.
• 🍔 Ecological Footprint: Measures human demand on Earth's ecosystems. Expressed in global hectares (gha).
• 🐾 Biodiversity: The variety of life at all levels of biological organization, from genes to ecosystems. Includes species diversity, genetic diversity, and ecosystem diversity.
• ⚠️ Threats to Biodiversity (HIPPO): Habitat destruction, Invasive species, Pollution, Population growth, and Overexploitation.
• ⚖️ Rule of 70: Used to estimate the doubling time of a population: $Doubling Time = \frac{70}{Growth Rate}$ (where growth rate is a percentage).
• 🌍 Sustainable Consumption: Using resources at a rate that does not deplete them for future generations.
