Population ecology is the study of populations in relation to environment, including environmental influences on density and distribution, age structure, and population size Concept: Dynamic biological processes influence population density, dispersion, and demographics A population is a group of individuals of a single species living in the same general area Density and Dispersion Density is the number of individuals per unit area or volume Dispersion is the pattern of spacing among individuals within the boundaries of the population Environmental and social factors influence spacing of individuals in a population Density: A Dynamic Perspective In most cases, it is impractical or impossible to count all individuals in a population

Campbell's Biology, 9e (Reece et al.) Chapter 1 Introduction: Themes in the Study of Life This introductory chapter explores the basic themes and concepts of biology, with emphasis on the core theme of evolution. It also introduces students to the thinking of scientists. Questions are therefore general; however, an effort has been made to include some from each skill level. As in the rest of this test bank, questions that feature art or those for which several questions follow upon some data or a scenario are placed together at the end of the chapter. Multiple-Choice Questions 1) A localized group of organisms that belong to the same species is called a A) biosystem. B) community. C) population. D) ecosystem. E) family. Answer: C Topic: Concept 1.1

Lesson Overview 3.3 Energy Flow in Ecosystems Lesson Overview Energy Flow in Ecosystems THINK ABOUT IT What happens to energy stored in body tissues when one organism eats another? Energy moves from the ?eaten? to the ?eater.? Where it goes from there depends on who eats whom! Lesson Overview Energy Flow in Ecosystems Food Chains and Food Webs How does energy flow through ecosystems? Energy flows through an ecosystem in a one-way stream, from primary producers to various consumers. Lesson Overview Energy Flow in Ecosystems Food Chains A food chain is a series of steps in which organisms transfer energy by eating and being eaten. Food chains can vary in length. An example from the Everglades is shown. Lesson Overview Energy Flow in Ecosystems Food Chains

Bio I Unit 7: Ecology Name KEY 3.1 What Is Ecology? Studying Our Living Planet 1. What is ecology? It is the scientific study of interactions among organisms and between organism and their environment. 2. What does the biosphere contain? It contains all the organisms and physical environments of the Earth. 3. How are human economics and ecology linked? Economics has to do with human ?houses? and interactions based on money and trade. Ecological interactions have to do with nature?s ?houses? and are based on energy and nutrients. Humans depend on ecological processes to provide nutrients that can be bought or traded. 4. Label each level of organization on the diagram.
