UNIT 15 - ECOLOGY List of Terms Ecology: study of interactions of organisms with their environment and with each other Population: group of individuals of one species in one area that can breed and interact with one another Community: all the organisms in one area Ecosystem: All the organisms in an area and abiotic factors in that area Abiotic factors: nonliving, include temperature, water, sunlight, wind, rocks, etc. Biosphere: global ecosystem Biotic potential: max rate at which a population can increase under ideal conditions Influenced by factors like age at which reproduction begins, lifespan during which you can reproduce, # of reproductive periods in lifetime, and the max # of offspring the organism can produce

Biomass ? Organic Matter One of our oldest energy sources. Gets energy from the sun-photosynthesis Renewable Three types are used today Wood and agriculture products Solid Waste Landfill gas and biogas What is it? ? How Does it Work? ? Mainly used for Electricity - 14% Heat- 1/10th of homes Fuels - 15% Industrial - 55% What Does it Do? ? Can be sustainable Paper and saw mills But? Like anything can be overused Cost How Realistic is it? ? Promising Comes from many different sources Usually our waste Can be used for a lot Has a few disadvantages Releases carbon dioxide Future? ? What is the purpose that biomass is used for the most? Where does biomass get its energy from? Is biomass better environmentally and economically than coal? How?

Cp. 3 Living in the environment

Cp 3 Ecosystems, What are they and How do They Work? p. 62 1. Define biomass 2. Give an everyday example. 3. Because the transfer of energy through the food chains and webs is not very ______________, some chemical energy is lost to the environment as ______-_______ _______. 4. What is ecological efficiency? 5. Give the range and the typical (specify which is which). 6. Prepare an Energy pyramid, start at 100,000 Calories Give all alternative names for each level. p. 63 7. The energy flow pyramids explain what about human populations? 8. About two thirds of the world?s human population survive on which foods? Why? p. 64 9. Why are food chains rarely more than 4 at the most 5 levels? 10. What is Gross primary producitivity? 11. How is it measured?

Characteristics of life, and definition of life: Life is characterized by (1) organization, (2) acquisition of materials and energy, (3) reproduction, (4) responses to stimuli, (5) homeostasis, (6) growth and development and (7) the capacity to adapt. Classification system to group organisms (DKPCOFGS): Systematics: Domain, kingdom, phylum, class, order, family, genus, species.

Chapter 3 ? Water & Fitness of the Environment Effect of Water?s Polarity Polarity of water causes hydrogen bonding Water is made up of 2 hydrogen and 1 oxygen; held together by 1 covalent bond Oxygen is slightly negative and hydrogen is slightly positive ?> polarity Polarity causes hydrogen to be attracted to other oxygen molecules, creating hydrogen bonds; each molecule can be connected to 4 other molecules 4 properties of water Water?s cohesion Stabilization of temperature Expansion upon freezing Versatility as a solvent Cohesion of water molecules Hydrogen bonds keep water molecules sticking together - hydrogen bonds are very weak; they form and reform with great frequency Cohesion: the process in which hydrogen bonds hold the substances together
