Ecology

 * Students will describe and explain the cycling of matter and flow of energy through an ecosystem’s living and non-living components.
 * Student will describe how the environment and interactions between organisms can affect the number of species and the diversity of species in an ecosystem.


 * 1) Differentiate between biotic and abiotic
 * 2) describe the reactants and products of photosynthesis and respiration
 * 3) compare and contrast the water, carbon/oxygen and nitrogen cycles
 * 4) Explain the need for energy in living systems
 * 5) Trace the flow of energy in a system
 * 6) explain how adaptations of species and co-evolution with other species are related to success
 * 7) identify examples of mutualism, commensalism, and parasitism
 * 8) predict and analyze how change in an ecosystem can affect the number of organisms in a population and biodiversity of a species in the ecosystem.

__Task 1__

__Biotic and Abiotic__

 * OR **


 * 1) Selected readings or clips:
 * 2) Read the “atom x” excerpt from a Sand County Almanac.
 * 3) Diagram the path of the atom
 * 4) Identify the biogeochemical cycle the atom belongs to
 * 5) Locate 2 additional essays or view a video about cycles in nature
 * 6) summarize the material in paragraph form
 * 7) identify the cycles presented

**What is a biogeochemical cycle? How are abiotic and biotic things involved in cycles in nature? How are the cycles in nature connected?**
 * Discuss with the teacher: **

Energy flow and succession

 * 1) Research producers and consumers. Compare and contrast your findings using the t-chart
 * 2) Reserach different types of vores (herbivore, omnivores, carnivore) and record your findings in the branch diagram
 * 3) view the video from 4:19 - 7:29 and write a summary / reflection on the news story. media type="custom" key="22567782"
 * 4) Choose one of the following tasks to complete


 * 1) Report on the importance and dangers of wildfires. Include references to maintaining or regenerating prairies and also the Yellowstone Fires. Some helpful sites are: (yellowstone or video)

 * OR **


 * 1) View one of the following videos and trace the energy flow through the system. Be sure to note interruptions in the flow and their impacts!
 * Crash: A Tale of Two Species []
 * Frogs: The Thin Green Line []
 * Holy Cow: []
 * Silence of the Bees: http://video.pbs.org/video/995224587/

Adaptations

 * 1) Explore the website and links at [] & []
 * 2) create a document of your learning (powerpoint, poster, brochure, essay, glog or presentation)


 * Discuss with the teacher: What is evolution? What is the difference between an analogous and homologous feature? Identify and compare one homologous feature found in at least 3 different organisms. Identify one vestigial feature and hypothesize as to its original purpose.**

Biome project

 * 1) Complete the biome project booklet. You may select any biome to use as the focus of your booklet, but you must use the same biome throughout the entire booklet. If you choose a mountain biome or a water biome, be sure to identify a specific location and use that as the source of information for your booklet.


 * Discuss with the teacher: What is a biome? What are the characteristics of the different biomes? What are the relationships among organisms in a biome? What are the relationships among living and nonliving things in a biome? How are biomes changing because of human behavior? How can an individual lessen the human impact on the world’s biomes?**

Invasive or endangered Species Project
