1. Across the top of a sheet of paper, list the different types of foods you ate for dinner last night. 2. Under each item, write the name of the plant, animal, or other organism that was the source of that food. Some foods have more than one source.

1. Three energy roles?  Producers  Consumers  Decomposers

2. Producers? Autotrophs 3. Consumers and decomposers Heterotrophs

4. What’s the difference?  Herbivores eat only plants  Carnivores eat only animals  Omnivores eat both plants and animals  Scavengers feed on the bodies of dead organisms

1. What is the difference between a food web and a food chain? 2. What are the 3 energy roles organisms have in an ecosystem? 3. Create a food chain that goes to a second level consumer.

5. Food chain?  Movement of energy through an ecosystem  Begins with producers  Food chain is specific

6. Diagram pgs Food web:  Movement of energy through an ecosystem  Many overlapping food chains

 Bill Nye the Science Guy - "It's The Food Web" - YouTube Bill Nye the Science Guy - "It's The Food Web" - YouTube

8. Energy Pyramid? It shows how energy decreases at higher levels of a food web

9. Eating the Sun?  Producers (autotrophs) convert the sun’s energy  You either eat the producers  Or you eat the animals that eat the producers

 Complete the Energy- Role walk activity on page 715. List 20 producers, consumers, and decomposers that you see. Create a list of the organisms and their energy roles. For each consumer, try to classify it further according to what it eats and its level. Then draw a energy pyramid for at least one food chain. This is a QUIZ grade!!!

1. What are the three forms of water? 2. What does evaporation mean, give an example? 3. What is the difference in condensation and Precipitation? 4. What is groundwater? 5. The suffix –ion means action or process, explain why that would be important with the water cycle. (look at key words)

 Evaporation: water changes to water vapor (gas)  Condensation: water vapor rises, cools, and turns back to liquid

 Precipitation: The water vapor droplets grow larger and larger until they fall back to Earth cfp&wcsuffix=4024&area=view&x=13&y=11 cfp&wcsuffix=4024&area=view&x=13&y=11

 Glacier, stream, ocean, cloud, stream, animal, cloud, glacier, ocean  “I was a lonely water molecule frozen in a glacier on top of a mountain. When the spring came and the ice thawed, I melted into a stream. Down the mountain, the stream roared going over large boulders. After the long journey I reached the ocean.”

1. What organisms only eat plants? a. producersb. consumersc. decomposers d. herbivores 2. What organisms get their energy by releasing chemicals onto another organism and then soaking it into their bodies? a. producersb. consumersc. decomposers d. herbivores 3.What organisms are able to produce their food? a. producersb. consumersc. decomposers d. herbivores 4. What organisms must take in other organisms to get energy? a. producersb. consumersc. decomposers d. herbivores 5.What organisms eat both plants and other animals? a. producersb. carnivoresc. omnivoresd. herbivores 6.Where is the largest amount of energy found on an energy pyramid? a. topb. middlec. bottomd. each level is the same

11. Forest fires?  During fires, lots of CO 2 are released into the air  Fire leaves fewer trees to absorb the CO 2  Too much CO 2 warms the atmosphere

12. How humans affect cycles.  Burning fuel and clearing forested land raises CO 2  Lowers oxygen levels in the air

13. How does nitrogen get returned?  Bacteria release nitrogen into the air  Decomposers break down wastes and remains returning them to the soil

14. Nitrogen-fixing bacteria? Live in nodules on the roots of plants 15. Biogeography? The study of where organisms live

16. Continental Drift?  Millions of years ago, the continents drifted apart  The continents drifted based on tectonic plates  &wcsuffix=1015&area=view&x=11&y=11 &wcsuffix=1015&area=view&x=11&y=11 &wcsuffix=1015&area=view&x=11&y=11

17. Organism dispersal? Wind, water, or other living things, including humans 18. Limits to dispersal?  Physical barriers (mountains)  Competition  Climate

19. Mountain climate change?  At the base it is warm and dry  At the top it is cold and windy

20. Biomes?  A group of land ecosystems with similar climates and organisms  Climate, temperature, and precipitation

21. Map on page 729? Along the equator 22. Giant Redwood trees  Northwest coast of the U.S.  Temperate rain forests

23. Canopy and Understory?  Canopy is the leafy roof of tall trees

23. Canopy and Understory? The understory is the second layer of shorter trees and vines under the canopy

24. Desert climate conditions?  Usually hot/dry during the day  Cooler at night  Receiving less than 25 cm of rain per year

Prairie: A grassland that receives more rain than a desert, but not enough to grow trees

Savanna: A grassland that receives more rain than prairies with scattered shrubs and small trees

26. Deciduous forests?  Receives less rainfall than rain forests  Temperatures vary by season  Trees shed their leaves

27. Map on page 734?  Cold winters  Coniferous trees  Found in on the northern parts of the northern hemisphere

28. Permafrost? Soil that is frozen all year long

Arctic Tundra: The extremely cold, dry part of the arctic

Alpine Tundra: The icy, windy tops of mountains

30. Freshwater ecosystem? Freshwater ecosystems include streams, rivers, ponds, and lakes Marine ecosystems are salt- water and part of the ocean

31. Estuary: Where fresh river water meets the ocean’s salt water

31. Intertidal Zone:  On the shore, between the highest tide line and the lowest tide line  See page 738

31. Neritic Zone:  The area from the low-tide line out to the continental shelf  See page 738

31. Oceanic Zone:  Out over the open ocean  From the surface down as deep as light penetrates  See page 738

31. Benthic zone:  Over open ocean  From just below the surface zone to the ocean floor  No light penetrates  See page 738
