Basic Scientific Concepts Organic vs. Inorganic: The primary difference between organic compounds and inorganic compounds is that organic compounds always contain carbon while most inorganic compounds do not. Also, all organic compounds contain carbon, hydrogen or C-H bonds. Ex. of Organic Compounds: Nucleic Acids, Fats, Sugars, Proteins, Enzymes, Fuels, DNA, and Methane CH4 Ex. of Inorganic Compounds: Salts, Metals, Table Salt and Carbon Dioxide Gene: A unit of heredity; a segment of DNA nucleus of the cell that contains information for the synthesis of a specific protein. Ex: Enzymes Gene pool: Combined genetic information, such as alleles, of all the members of a particular population.

August 2013 Chapter 22 Descent with Modification A Darwinian View of Life Darwin introduces a new theory Charles Darwin published On the Origin of Species by Means of Natural Selection on November 24, 1859 It focused on the diversity of organisms Their origins and relationships Their similarities and differences Their geographic distribution Adaptation to surrounding environments Presented evidence that many species from earth are descendants of ancestral species that were different from the modern species Proposed a mechanism for this process, which name is Natural Selection Natural Selection is that a population can change over generations, leaving heritable traits to their breeds, this population can get a lot of changes that can eventually form to a new specie

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.

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

Unit I: The Concept of Life Biology : The Study of Life How is Life Defined? Key Idea: All living things carry out eight essential life functions. Collectively, the eight life functions are known as metabolism. Nutrition: the process in which food (organic molecules) is absorbed (ingestion) and used or broken down (digestion). Transport: the process in which material is moved from one place to another (circulated) within organisms. Active Transport: the type of transport that moves material from a low to high concentration while using energy.
