AP Biology Reading Guide Chapter 52 An Introduction to Ecology and the Biosphere Fred and Theresa Holtzclaw Copyright ? 2010 Pearson Education, Inc. - 1 - Name________________________________ Period___________ Chapter 52: An Introduction to Ecology and the Biosphere Overview 1. What is ecology? 2. Study Figure 52.2. It shows the different levels of the biological hierarchy studied by ecologists. Notice also the different types of questions that might be studied by an ecologist at each level of study. Use this figure to define or explain the following terms: organismal ecology population population ecology community community ecology ecosystem ecosystem ecology landscape ecology biosphere global ecology

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.

Ecology Study Guide Notes Chapter 50: Intro to Ecology The Scope -3 main questions: Where do they live? Why do they live where they do? How many are there? -Ecology helps reveal the richness of the biosphere and helps humans understand how to protect that diversity and richness which is now under attack. 50.1 Ecology is the study between organisms and the environment - Naturalists began studying organisms in their environment. Humans have also had need to know about organisms for hunting and gathering. - Ecology is very much an experimental science (field experiments). The difficulty to provide consistent results has resulted in many innovations regarding experimental science. Ecology and Evolution

ECOSYSTEMS: COMPONENTS, ENERGY FLOW & MATTER CYCLING CHAPTER 4 ECOLOGY Study of the relationships between organisms and their environment How organisms interact with their nonliving environment such as sunlight, temperature, moisture, nutrients, etc. KEY WORK IS: INTERACT - Connections in Nature What is an organism? What make up organisms? Organisms are either: EUCARYOTIC - SURROUNDED BY A MEMBRANE HAVE A DISTINCT NUCLEUS HAVE INTERNAL ORGANELLES All organisms except bacteria. PROCARYOTIC - SURROUNDED BY A MEMBRANE NO DISTINCT NUCLEUS NO INTERNAL PARTS SURROUNDED BY MEMBRANES Bacteria What is a SPECIES? How do species differ? What is the difference between sexual and asexual reproduction? Number of species on earth is not known 5 million to 100 million maybe

Ecology -The study of how organisms interact with one another and their physical environment of matter and energy. All living organisms are composed of cells. Cell-the smallest and most fundamental structural and functional units of life. The idea that all living things are composed of cells is called cell theory. Organisms can be classified as either eukaryotes or prokaryotes A eukaryote is a cell surrounded by a membrane that has a distinct nucleus and other internal parts called organelles. A prokaryote is a cell surrounded by a membrane but has no distinct nucleus or organelles surrounded by membranes. For a group of sexually reproducing organisms a species is a set of individuals that can mate and produce fertile offspring.
