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.

POD # 19 Where did your dinner come from?

Ecosystems and Biomes

1. Three energy roles?

Producers Consumers Decomposers

Ecosystems and Biomes

2. Producers?Autotrophs3. Consumers and

decomposersHeterotrophs

Ecosystems and Biomes

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

Ecosystems and Biomes

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.

POD # 20 Food Web and Food Chain

5. Food chain? Movement of

energy through an ecosystem

Begins with producers

Food chain is specific

Ecosystems and Biomes

6. Diagram pgs 712-713

7. Food web: Movement of energy

through an ecosystem

Many overlapping food chains

Ecosystems and Biomes

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

Ecosystems and Biomes

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

Ecosystems and Biomes

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)

POD #21 Water Cycle

Evaporation: water changes to water vapor (gas)

Condensation: water vapor rises, cools, and turns back to liquid

10. The Water Cycle?

Precipitation:The water vapor

droplets grow larger and larger until they fall back to Earth

10. The Water Cycle?

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.”

Water molecule story…

1. What organisms only eat plants?a. producersb. consumersc. decomposers d. herbivores2. What organisms get their energy by releasing chemicals onto

another organism and then soaking it into their bodies? a. producersb. consumersc. decomposers d. herbivores3.What organisms are able to produce their food?a. producersb. consumersc. decomposers d. herbivores4. What organisms must take in other organisms to get energy?

a. producers b. consumersc. decomposers d. herbivores

5.What organisms eat both plants and other animals?a. producersb. carnivores c. omnivores d. herbivores6.Where is the largest amount of energy found on an energy

pyramid?a. top b. middle c. bottom d. each level is the same

POD # 22 Energy flow review

11. Forest fires? During fires, lots of

CO2 are released into the air

Fire leaves fewer trees to absorb the CO2

Too much CO2 warms the atmosphere

Ecosystems and Biomes

12. How humans affect cycles.

Burning fuel and clearing forested land raises CO2

Lowers oxygen levels in the air

Ecosystems and Biomes

13. How does nitrogen get returned?

Bacteria release nitrogen into the air

Decomposers break down wastes and remains returning them to the soil

Ecosystems and Biomes

14. Nitrogen-fixing bacteria?

Live in nodules on the roots of plants

15. Biogeography?The study of where

organisms live

Ecosystems and Biomes

16. Continental Drift? Millions of years

ago, the continents drifted apart

The continents drifted based on tectonic plates

17. Organism dispersal?Wind, water, or other living

things, including humans18. Limits to dispersal? Physical barriers

(mountains) Competition Climate

Ecosystems and Biomes

19. Mountain climate change?

At the base it is warm and dry

At the top it is cold and windy

Ecosystems and Biomes

20. Biomes? A group of land

ecosystems with similar climates and organisms

Climate, temperature, and precipitation

U.S. Temperate rain forests

23. Canopy and Understory?

Canopy is the leafy roof of tall trees

Ecosystems and Biomes

23. Canopy and Understory?

The understory is the second layer of shorter trees and vines under the canopy

Ecosystems and Biomes

24. Desert climate conditions? Usually hot/dry during the

day Cooler at night Receiving less than 25 cm

of rain per year

Ecosystems and Biomes

Prairie: A grassland that receives more

rain than a desert, but not enough to grow trees

25. Savannas vs. Prairies?

Savanna:A grassland that receives more

rain than prairies with scattered shrubs and small trees

25. Savannas vs. Prairies?

26. Deciduous forests? Receives less rainfall than

rain forests Temperatures vary by

season Trees shed their leaves

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
