Ecology Study Guide Chapter 51 Animal behavior is anything to do with animals and they way they function and reproduce. Proximate cause is the immediate trigger for a behavior. For example, if a zebra is drinking at a water hole, and all of a sudden it hears another zebra nearby make an alarm call, it may stop drinking immediately and start running away instead. The proximate cause of the zebra running away would be the alarm call. But the ultimate cause, or real reason why the zebra is running is survival. It is running away because it wants to survive. The alarm call is not the source of danger, but the alarm call alerts the zebra that danger, such as a lion, may be nearby and the lion can threaten the zebra's chance to survive.

Chapter 3 abiotic Two types of components make up the biosphere and its ecosystems: One type, called abiotic, consists of nonliving components such as water, air, nutrients, rocks, heat, and solar energy. aerobic respiration Producers, consumers, and decomposers use the chemical energy stored in glucose and other organic compounds to fuel their life processes. In most cells this energy is released by aerobic respiration, which uses oxygen to convert glucose (or other organic nutrient molecules) back into carbon dioxide and water. anaerobic respiration, or fermentation Some decomposers get the energy they need by breaking down glucose (or other organic compounds) in the?absence?of oxygen. This form of cellular respiration is called anaerobic respiration, or fermentation.

Principles of Ecology Organisms and Their Environment What is Ecology? Ecology: the study of interactions that take place between organisms and their environment The Biosphere Biosphere: the part of Earth that supports life The biosphere includes the top portion of Earth?s crust, all the waters that cover Earth?s surface, and the atmosphere that surrounds Earth. The biosphere is made up of different environments that are home to different kinds of organisms. Ecosystem: all the living organisms living in an area and the nonliving features of their environment Biotic factors: living organisms in an ecosystem (ex. bison, grass, birds, insects) Abiotic factors: nonliving features of an ecosystem (ex. water, temperature, sunlight, soil, air) Levels of Organization

Chapter 3 Notes Ecosystem Boundaries Biotic and abiotic components of an ecosystem provide the boundaries that separates them from one another Some have a well-defined boundaries: Like a cave Scientist might define a terrestrial ecosystem as the range of a particular species of interest Ecosystems occur in a wide range of sizes Ecosystem Process Each ecosystem interacts with surrounding ecosystems Change in ONE ecosystem can affect the global environment Photosynthesis and Respiration Nearly all of the energy that powers ecosystems comes from the sun Plants, algae and other organisms have the ability to convert the suns solar energy to usable from of energy, these are called producers/autotrophs

Bio 112 April 29th, 2013 More on Ecosystems Food webs -Is a branching food chain with complex trophic interactions -Including decomposes (detritevors) Energy Flow through Ecosystems -from one trophic level to the next. Primary production - are photoautotrophs, capturing energy from the sun. Energy flows from these guys through all other levels. Of course some energy will be lost at each level. -light energy converted to chemical energy by autorophs during a given time period. -Gross primary production is the total primary production. -Net primary production is GPP minus energy used by producers (respiration)-only this is available to consumers. NPP is more important then GPP. Secondary production

Environmental Science Vocabulary ? Living Things in the Environment & Populations organism - a living thing habitat - an environment that provides the things an organism needs to live. biotic factor - a living part of an organism?s habitat. i.e. grass, plants, seeds, fruit, worms, bacteria, other animals abiotic factor - a non-living part of an organisms habitat. i.e. water, sunlight, oxygen, temperature, soil photosynthesis - the process in which plants use water along with sunlight and carbon dioxide to make their own food. species - a group of organisms that are physically similar and can produce offspring. population - all the members of one species in a particular area. The ?count? of one species in an area.

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.
