AP Biology Questions on Animal Communication and Behavior

🧬 Quick Study Guide

• 👂 Forms of Communication: Animals communicate using visual, auditory, chemical, tactile, and electrical signals. The type of signal used often correlates with the animal's environment.
• 🐜 Pheromones: Many animals, particularly insects, use pheromones for communication related to mating, alarm, and trail-marking.
• 💃 Behaviors: Innate behaviors are genetically inherited, while learned behaviors develop through experience.
• 🦉 Fixed Action Patterns (FAPs): These are unlearned behaviors triggered by a sign stimulus. Once initiated, the FAP is usually completed.
• 🧭 Migration: Some animals undertake long-distance migrations, often using environmental cues like the sun, stars, and Earth’s magnetic field for navigation.
• ❤️‍🔥 Altruism: Some animals exhibit altruistic behavior, which can be explained by kin selection (increasing the survival of relatives).
• 🕰️ Circadian Rhythms: Daily cycles of activity influenced by internal biological clocks.
• ⚖️ Optimal Foraging Theory: Predicts that animals will forage in a way that maximizes the energy gained per unit of time.
