What is your assigned nutrient cycle?

Transcription

1 Name: Date: Period: Learn and Teach the Nutrient Cycles a. You will be working in groups of 3 or 4 list your group members name & their assigned cycle: Name Cycle What is your assigned nutrient cycle? b.while you are in your group, you will be researching the nutrient cycle that you were assigned & answering the following questions. As a group, you are going to obtain as much information about your assigned nutrient cycle as you can today. Initial Research Questions: 1.Define the cycle in your own words. 2.What events/steps happen in the cycle? 3. Define new terminology that you encounter when researching your assigned cycle. 4.What is the purpose of this cycle?

2 5.How does it affect your everyday life? 6.What other events in nature (photosynthesis, cellular respiration, etc ) are affected by this cycle? 7.Is there an environmental concern about this cycle?

3 In your group of 4 devise a powerpoint that meets the following requirements: Content Criteria: Completely answers the specific research questions for that nutrient cycle from the attached handout Nutrient Cycles All 4 nutrient cycles are represented Formatting Criteria: Share with me at lmilani@srvusd.net Share with Mrs. Milani as google slides named by listing all of your group members names first and last: Ex. BartSimpson,LisaSimpson,MaggieSimpson, and Milhouse VanHouten Group name and graphic on Title Slide with all group members names on it, the period and date. Second slide is Table of Contents Slide with an ability to select a nutrient cycle and go to that slide.

4 Nutrient Cycles: Name of Nutrient Cycle: THE WATER CYCLE 1.Define the water cycle: 2.Diagram the abiotic source of water and how it enters organisms, cycled through ecosystems and is returned to the abiotic source include human impacts to the cycle. 3.Define key terms that are in the water cycle: Evaporation: Transpiration: Condensation: Precipitation: Seepage: Root Uptake: Runoff: Why is this cycle important in nature and living organisms? Describe how humans can affect this cycle. (Hint# pollution) Name of Nutrient Cycle: THE CARBON CYCLE 1.Define the carbon cycle: 2.Diagram the abiotic source of carbon (carbon dioxide) and how it enters organisms, is cycled through ecosystems and is returned to the abiotic source: Include human impacts to the cycle. Photosynthesis: Decomposition: Respiration: Erosion: Why is this cycle important in nature and living organisms? Describe how humans can affect this cycle. (*Hint: fossil fuels)

5 Name of Nutrient Cycle: THE NITROGEN CYCLE 1.Define the nitrogen cycle: 2.Diagram the abiotic source of nitrogen and how it enters organisms, is cycled through ecosystems and is returned to the abiotic source: Include human impacts to the cycle. Nitrogen fixation: Denitrification: Why is this cycle important to nature and living organisms? How do living organisms use nitrogen? Describe how humans can affect this cycle. Name of Nutrient Cycle: THE PHOSPHORUS CYCLE 1.Define the phosphorus cycle: 2.Diagram the abiotic source of phosphorous and how it enters organisms, is cycled through ecosystems and is returned to the abiotic source: Include human impacts to the cycle. Weathering: Inorganic phosphates: Why is this cycle important to nature and living organisms? How do living organisms use phosphorous? Describe how humans can affect this cycle.
