The following document consists of the lab report, graphs and write up of the Arthropod Lab that is worth more than 20% of the BIO251 Ecology course in AUS, the American University of Sharjah.

Chapter 1: Introduction to Economics An overview of fundamental economic concepts including scarcity, opportunity cost, and resource allocation. Introduces economic thinking, the difference between microeconomics and macroeconomics, and the basic economic questions all societies must answer. Covers economic models, positive versus normative analysis, and the production possibilities frontier to illustrate trade-offs and efficiency.

Chapter 2: Supply and Demand Explores the core model of market interactions through supply and demand analysis. Examines determinants that shift supply and demand curves, market equilibrium, and how prices and quantities adjust. Demonstrates graphical analysis of markets and introduces consumer and producer surplus concepts as measures of market welfare.

Chapter 3: Elasticity Focuses on measuring responsiveness in economic relationships through elasticity concepts. Covers price elasticity of demand, price elasticity of supply, income elasticity, and cross-price elasticity. Includes calculation methods, interpretation of elasticity values, and applications to business decisions and government policies like taxation.

Chapter 4: Consumer Theory Examines how consumers make choices to maximize utility given budget constraints. Explores indifference curves, budget lines, utility maximization, and consumer preferences. Analyzes how changes in income and prices affect consumer choices and introduces consumer surplus as a measure of consumer welfare.

Chapter 5: Production and Costs Investigates how firms transform inputs into outputs and the costs associated with production. Covers production functions, diminishing returns, economies of scale, and various cost concepts (fixed, variable, marginal, average). Explains short-run versus long-run cost structures and their implications for business decision-making.

Chapter 6: Perfect Competition Analyzes the perfectly competitive market structure where many firms sell identical products with no barriers to entry. Examines firm behavior in the short run and long run, including profit maximization, shutdown decisions, and market equilibrium. Demonstrates how perfect competition leads to economic efficiency.

Chapter 7: Monopoly Studies markets dominated by a single seller with significant market power. Explores how monopolists determine price and output to maximize profits, the sources of monopoly power, and the resulting inefficiencies. Compares outcomes under monopoly to perfect competition and introduces price discrimination strategies.

Chapter 8: Market Structures Between Perfect Competition and Monopoly Examines intermediate market structures including monopolistic competition and oligopoly. Covers product differentiation, non-price competition, strategic interaction among firms, and basic game theory concepts. Analyzes how these market structures affect pricing, output decisions, and economic efficiency.
