1 Ecosystem Poster By the end of this lesson you will: Understand the complexities and intricacies of how ecosystems work. o Understand and explain in depth the relationship between organisms and the abiotic and biotic factors within their environment o How factors such as food, water, shelter, and space affect populations in an ecosystem Directions create an ecosystem visually showing biotic and abiotic factors unique to that ecosystem. You must have a works cited page, so remember to record your sources on the worksheet as you complete each part. 1. Pick an ecosystem (be sure a water source is included): a. Deciduous Forest b. Desert c. Ocean d. Taiga e. Temperate Forest f. Tropical Rainforest g. Tundra h. Wetlands 2. Define abiotic and biotic factors and give an example of each within your ecosystem 3. Identify a minimum of 15 organisms from that ecosystem a. You must have at least one organism from each of the following types i. terrestrial animal ii. aquatic animal iii. a plant b. For all of your selected organisms identify if it s a producer, consumer, or decomposer c. Create 5 food chains that make up 1 food web involving all of these organisms i. Be sure to include the ultimate source of the earth s energy source within your food web ii. Make sure the food web connects aquatic and terrestrial organisms iii. Give an example for each of the following relationships: d. For one producer and one consumer within your food web, what effect would it have if their population increased? Decreased? 4. Identify the top 2 pollutants of your ecosystem a. How are they harming the ecosystem? b. Are they point source or nonpoint source pollutants? c. How do they affect the water quality of the ecosystem? (Refer to the previous unit on water quality) 5. Written explanation (individually done) a. Choose four organisms and explain how they interact with and respond to abiotic and biotic components within their environments. Include positive and negative outcomes that might happen due to these interactions. i. Example (your response will be in paragraph form) 1. Biotic a mouse eats grass; grass provides nourishment to live within its ecosystem. 2. Abiotic mouse burrows into the soil; it s using the soil for shelter. 1

2 Rubric Criteria Possible Points Earned Points Worksheet: Pick an ecosystem (water source is included) Define abiotic and biotic factors and give an example of each within your ecosystem (2 pt.) Identify a minimum of 15 organisms There is at least one organism from each of the following types terrestrial animal, aquatic animal and a plant For each organism - identify if it s a producer, consumer, or decomposer 12.5 points Food Web and Relationships Create 5 food chains that make up 1 food web involving all organisms The food web includes the ultimate source of the earth s energy and connects aquatic and terrestrial organisms. Give an example for each of the following relationships: Select one producer and one consumer within your food web. The effect if their population increased? Decreased? 12 points Pollutants of your Ecosystem Identify the top 2 pollutants of your ecosystem How are they harming the ecosystem? Identify if point source or nonpoint source pollutants How do they affect the water quality of the ecosystem? 4 points Written Explanation (in paragraph form) Choose four organisms - explain how they interact with and respond to abiotic and biotic components within their environments. Include positive and negative outcomes that might happen due to these interactions points Poster, Professionalism, & Effort Poster includes all required information. 1. Food Web 2. Pollutants 3. Abiotic & Biotic Factors 4. Relationships 5. Population Increase & Decrease Project is neat and professional; Used time wisely during class Overall, quality of work compared with both past work and increasing expectations of better work. 10 points Presentation Present ecosystem poster to the class Must be professional when presenting 5 points Works Cited/Sources At least 7 different sources Cite sources according to MLA format (see help sheet) Include a Works Cited page for all the sources on the poster (can be pasted onto back) This is a major assessment grade. Total 2 points 50 2

3 Ecosystem: (1/2 point) Research Worksheet ABIOTIC: Ex: BIOTIC: Ex: Organism Producer, Consumer, or Decomposer 1. Producer 2. Producer 3. Producer 4. Producer 5. Producer Terrestrial, Aquatic, or Plant 3

4 Give an example for each of the following relationships: (1/2 point each) Food Chains: (1 point each) MUST HAVE 15 ORGANISMS TOTAL FOOD CHAINS START WITH A PRODUCER Producer: (2 points) 1. Population Increase 2. Population Decrease Consumer: (2 points) 1. Population Increase 2. Population Decrease 4

5 Top 2 pollutants: (2 points per pollutant) 1. Circle one: Point Source Nonpoint Source 2. How does this affect the water quality of the ecosystem? 1. Circle one: Point Source Nonpoint Source 2. How does this affect the water quality of the ecosystem? *Be sure to include your individually written explanation.* WORKS CITED/SOURCES (remember you need at least 7) 5
