chemosynthesis

Objectives: 1. Develop an explanation for why communities can thrive around vent communities 2. Identify what chemosynthesis is 3. Compare and contrast photosynthesis

Step 1: Step 2: Objective You are going to make a display that describes chemosynthesis and photosynthesis. Your display will include a poster with explanations.
 * 1) Your goal is to learn about hydrothermal vent communities in order to explain why they thrive.
 * 2) You can learn about hydrothermal vents in three ways
 * 3) Go through the slide show by pushing the arrows on the page and reading the descriptions under the pictures.
 * 4) Watching the video on hydrothermal vents
 * 5) Reading the article about hydrothermal vents
 * 6) As you read or watch the video think about the following questions:
 * 7) What is a hydrothermal vent, where they found, and what causes them to occur?
 * 8) What is chemosynthesis and what is it used for at the vent?
 * 9) What organisms use chemosynthesis?
 * 10) How is chemosynthesis similar to photosynthesis, and how is it different?
 * 11) What organism is the main producer in the vent community?
 * 12) Describe/draw a basic food chain in the hydrothermal vent.
 * 13) Describe the key symbiotic relationship found in hydrothermal vents
 * 14) What are the extreme abiotic factors found at the vent community that the organisms have to withstand?
 * 15) What causes hydrothermal vents to die out?

Poster
You need to have poster explaining the two processes. You can choose the format in which you would like to display your information. It can be a ven diagram, pictures, T-chart, etc. Things you need to include on your poster: The written equation of each process What organisms use each process What ecosystme each organism is generally found Why each process is important The main energy source used by each process Any relevant pictures
