CHAPTER 56 - AN INTRODUCTION TO ECOLOGY AND THE BIOSPHERE (Note Concept Outline at chapter beginning and Concept Reviews at the end of the chapter) Objectives: 1. Scope of Ecology What is an Ecosystem? – a Biosphere? What is Ecology? – an Ecologist? What are the areas of Ecology 2. What are the major properties of our Biosphere? Biotic Components Abiotic Components Gases Liquids Solids/Minerals 3. Factors that Effect the Distribution of Organisms Climate (temperature, moisture, etc) Soils Water Other organisms (competition, predation, immigrant survival probability – adaptation) 4. Examples of Distribution of Organisms Biogeographic Realms Biomes What is an Ecosystem? An ecosystem is any place in nature that has some degree of permanence and exhibits energy flow and nutrient/mineral cycling between the biotic (living) and abiotic (non-living) parts of the area. Let class give some examples – basically, an ecosystem is what an ecologist defines it to be. Individuals who study ecosystems are called ecologists Ecology is a term coined in 1869 by Ernst Haeckel – Greek Oikos which roughly means “house” or “habitat.” The largest ecosystem we know of is our own planet which is called a Biosphere . What are the major properties of our Biosphere? The biosphere is a narrow band, or mantle/cloak, of living matter around the surface of the Earth. It is roughly 5 miles high (mountains) X 5 miles deep (bottom of ocean trenches). Most organisms live in a more narrow band of ~ 3X 3 miles. Living organisms constitute the biotic components of this large ecosystem and consist of populations (individuals of one species) and communities (several populations). Abiotic Components : (Necessary for life as we know it) Gases: O 2 , N 2 , CO 2 , O 3 Liquids: H 2 0 in the form of rain, snow, ice, fog Liquid methane seems to be the liquid on Titan the largest moon of Saturn).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
