1 Name Period Plant/Ecosystems Webquest Log on to Username Password Click on My Content Click on the folder Ecosystem Click on A Biome to Call Home 1. Read Intro Define biome- 2.Fill in the following chart BIOME LOCATION CLIMATE(temp and prec) ANIMALS AND PLANTS Savannah Desert Prairie Taiga Chapparal Tropical Rain Forest Deciduous Forest Go back to the My Content Ecosystem folder and select Ocean Ecosystems. Click on the tab at the bottom of the page entitled START HERE. Read this overview. 3. A coral reef ecosystem can be very. 4. List some organisms found in a coral reef ecosystem. 5. What will you be investigating? 6. What are some of the variables you will be changing? 7. Why is it important to only change one variable at a time? Now click the tab entitled BACKGROUND. 8. What is an ecosystem? 9. What is the difference between biotic factors and abiotic factors? 10. List 2 biotic factors in the coral reef ecosystem.

2 11. List 2 abiotic factors. 12. What type of organisms make their own food in the coral reef ecosystem? 13. What type of organisms cannot make their own food, but eat the producers? 14. What type of organism break down dead plants and animals? 15. The transfer of energy in the form of food as one organism eats another is called a. 16. Energy is as it moves through a food web from a producer to a consumer to another consumer. Why? 17. Only about of the energy taken in by an organism is passed along to the next link in the food chain. 18. Algae in the coral reef ecosystem help add to the area. How do they do this? 19. What other producers are present in the coral reef? 20. There are no insects in the reef, but, and are the low-level (primary) consumers. 21. and are examples of top level consumers. Now go back to the main screen. Manipulate one variable at a time. Take notes below as to what happens when each variable is changed. (HINT: You might want to make a chart) Make sure you RESET between each variable change! Water temp Prod/consumer pop Human activity 22. What happened when you increased the algae? 23. What happened when you increased the parrot fish population? 24. What happened when you increased the tiger shark population? 25. What happens when human activity is at high use? Are all populations of reef species decrease? PREAP- Click on the Questions tab at the bottom of the page. Answer the questions on your own paper and staple them to this sheet.

3 Go back to the My Content Ecosystem folder and select Photosynthesis. Read the description. Answer the following questions you will need to click the list on the right side to move to new topics. 26. What is photosynthesis? 27. Organisms that conduct photosynthesis are considered the in their environment. 28. Reactants are the elements or compounds that go into a chemical equation (go before the arrow). What are the two reactants in the process of photosynthesis? 29. Products are the elements or compounds that come out of a chemical reaction. What are the two products in the process of photosynthesis? 30. The chloroplasts in the leaves contain a pigment called. 31. Chlorophyll absorbs energy and then converts it into energy. 32. Chlorophyll absorbs all wave lengths of light except and. That is why leaves appear green. 33. Carbon Dioxide enters plant leaves through the. 34. Transpiration is the evaporation of water from a leaf. Water enters the plant through the and then moves up the plant through the. 35. The movement of water up through the xylem is caused by in the leaves. 36. During photosynthesis light energy is converted to chemical energy or. 37. When eat producers, the chemical energy is transferred to them. 38. Oxygen exits the plant through the. 39. Most oxygen on Earth is produced by found in the oceans. After finishing the questions, take the Quiz at the bottom of the page. Write down your score.

4 Go back to the My Content Ecosystem folder and select Who s for Dinner. Read the Introduction and answer the following questions. 40. In an ecosystem, energy flows from the to producers. 41. Copy the animals names from the food chain onto this food chain 42. What animals in the food web might eat sea birds? Go back to the My Content Ecosystem folder and select What s Eating You. Read the Introduction and answer the following questions. 43. Producers use energy to make food. 44. Consumers get their energy (eat). 45. Decomposers break down material. 46. Food webs show the transfer between producer, consumers and decomposers. 47. Primary consumers eat and can also be called. 48. Look at the red lines. They represent energy that is not going up the energy web to the next animal, but energy that is converted to and given off into the atmosphere. 49. Which animal is a tertiary consumer? 50. List 2 examples of decomposers.
