Before Class Task 1. Hand in Reading Check page 115 and CYU Q1 and 9 2. Pick up Checklist for Chapter 3 3. Pick up Activity 3-1b information sheet 4. Match the plant or microorganism species (1-4) to their adapted environment (a-d).You will need to hand in with the activity project 1. Lichen 2. Mosses 3. Grasses 4. Shrubs 5. Tall Trees a. Bare Rock b. More decomposing material c. Some soil but mostly rock d. There is a decomposing layer built up e. A thick layer of decomposing layer Chapter 3 Class Schedule March 3rd and Mar 4th Chapter 3.1 Primary and secondary succession. Modeling in Ecosystem Assignment (page 118) March 5th and March 6th Continue Chapter 3.1 (page 118) March 7th and March 10th Chapter 3.2 How human influence ecosystem March 11th and March 12th Chapter 3.3 How introduced species affect ecosystem- Cane Toad Video Worksheet (Notebook Due) March 13th and March 14th Cane Toad Video Worksheet and note April 1st and April 2nd Test Review April 3rd and April 4th Chapter 3 test Announcement Office Hour: Lunch Time, Room 204. Come to ask me questions about: assignment due, project, notebook due, and test date Learning Journal Continue for Chapter 3- It is a study note and you should keep it updated as the class goes (due March 11, Chapter 3.1 and 3.2 up to date) Example: The Finches of the Galapagos Islands (off the coast of Ecuador) Finches: There are 13 species on the island… ECOLOGICAL SUCCESSION Changes in the biotic characteristics in an area over time. Primary Succession P111-113 Secondary Succession p114 1) Steps of Primary Succession (page 111) a. Starts with bare rock. b. Wind carries spores of lichens that can survive on bare rock. c. Weathering breaks down rock soil begins to form d. Pioneer species make/improve soil e. Other plants can grow f. Animals appear g.form a mature community (stable and change slowly) Pioneer Species are the first organisms to survive and reproduce. Examples: Lichens and mosses Lichen Bare rock Mosses Bare rock breaks down and create soil Grasses and shrubs Thin Layer of soil. A Decomposing layer start forming Deciduous Trees More decomposing layer and more mosit and fertile Very tall coniferous trees A very thick nutritious and fertile decomposing layer 2. Secondary Succession: when an area already has soil, but has had a disturbance like a forest fire or clearcut. Happens more quickly than primary because there are already seeds, insects, worms etc. in the soil. Activity 3-1 B Part 1 Format: Hand in individually, but you are welcome to work with a partner Instruction: Question (p118): recall the discussion on the similarity and difference between primary and secondary succession (1 point for similarity and 1 point for difference) Step 1: Put the stages in order.You need to check with me before you continue. (5 points) Step 2: Draw the illustration of the seven stages (1 point) Step 3: Select one of the natural disturbance (page 119) Step 4: Draw three sketches to illustrate the secondary succession (1 point) Activity 3-1 B Part 2 Format: Hand in individually, but you are welcome to work with a partner Instruction: Analyze: you need to write a paragraph that include and underline the following terms: pioneer organisms (0.5 point), changes (0.5 point), replaces (0.5 point), community (0.5 point), least biodiversity (0.5 point), most biodiversity (0.5 point), and mature community (0.5 point) (3.5 point in total) Compare the biotic similarity (0.5 point), difference (0.5 point), abiotic similarity (0.5 point), and abiotic difference (0.5 point) (2 points in total) Bonus mark (1 extra point) Put the stages in Before Class Activity in order Wrap up Hand in Check Your Understanding 2-7 on page 121 Read page 111 to 114. There will be competition in the beginning of next class Disturbances that Might Cause Secondary Succession Flooding Leads to soil erosion, spread of pollutants and harmful bacteria associated with sewage Climate change and global warming may be increasing incidents of flooding. A tsunami occurs when huge waves, from large earthquakes, flood coastal areas. Drought Insect infestation - Most insects are helpful, but when normal conditions change, infestations can occur. - Example: Mountain Pine Beetle: Usually it is not a problem…it helps remove old trees, but…. …in our forests there are a lot of old trees, the climate is warming, and the bugs are not dying in the winter. Pine beetle has blue stain fungus in its mouthparts, which it transmits to the trees (symbiotic relationship). Fungus slows down resin production on trees so the beetle can eat the tree more easily.
