 * State Standards: **

Energy and Living Things Standard #14:Explain the roles and relationships among producers, consumers, and decomposers in the process of energy transfer in a food web. Standard #15:Explain how dead plants and animals are broken down by other living organisms and how this process contributes to the system as a whole. Standard #16:Recognize that producers (plants that contain chlorophyll) use the energy from sunlight to make sugars from carbon dioxide and water through a process called photosynthesis. This food can be used immediately, stored for later use, or used by other organisms.


 * Major Learning Targets: **
 * I can explain and give examples of the energy roles in an ecosystem
 * Producers
 * Consumers
 * Decomposers
 * I can recognize what energy role an organism fills, if I am given their method of obtaining energy
 * I can construct a food webs and use it to show how energy moves through the ecosystem
 * I can interpret an energy pyramid is and name its trophic levels
 * I can explain why the number of organisms and the amount of available energy at each tropic level is different.


 * Important Concepts: **
 * Producers contain the most available energy in an ecosystem
 * Herbivores contain the next most energy
 * Carnivores and omnivores consist of even less
 * Energy is lost at every level to fuel organisms. Their bodies burn off energy as they carry out life processes
 * Invasive species can upset the balance of ecosystems
 * Important Skills: **
 * Be able to construct a food chain
 * Be able to construct a food web
 * Make a compost bin to observe decomposers at work
 * Assessments and Projects in Addition to Weekly Test:

[|Australian food web] Record your answers for each Austalian ecosystem on a piece of paper. Copy the grid as is and write in where you placed each organism

[|Another food web] Once you correctly place all the organisms, copy down the levels and write down which organisms you placed where. You do not need to draw all the arrows!!!

[|Virtual lab] Write down your top score after trying to answer the questions for all ecosystems

[|Create the web] Copy down each food web as you complete it.

[|Energy Roles] Record your answers

[|Analyzing an ecosystem] Write and record your answers to each question
