1. Energy in Ecosystems

2. Bell ringer Put all your stuff away along the side of the classroom.
Take out your notebook

3. WHAT DOES MOOFASA MEAN WHEN HE SAYS WE ARE ALL PART OF THE CIRCLE OF LIFE?

4. THE WEB OF LIFE

5. ECOSYSTEM EXAMPLES
What is an ecosystem?
Ecosystem: community of living and non-living organisms interacting with one another

6. DIFFERENT TYPES OF ECOSYSTEMS

7. What is the ultimate source of all energy?

8. ENERGY IN ECOSYSTEMS
Energy is recycled in an ecosystem because it cannot be created nor destroyed.

9. FOOD CHAIN
Food Chain: Single pathway of energy that shows interaction between organisms
Food Web: Multiple pathways of energy of ENTIRE ecosystem
Arrow points in direction of energy transfer and predator

10. FOOD CHAIN VS. FOOD WEB

11. ORGANISMS WITHIN AN ECOSYSTEM
Producers/ Autotrophs
Has the most energy
Makes their own food
Have the most energy in a food web because they get it directly from the sun!

12. Consumers/Heterotroph: get energy from eating other organisms (primary, secondary, tertiary, quarternary)
Apex Predator: top of the food chain
But wait, Moofasa mentioned that an ecosystem is a circle of life. What comes after the final consumer passes away?

14. THE END IS ONLY THE BEGINNING
Decomposers: Get energy from breaking down decaying organisms.
All organisms in the food chain are decomposed by decomposers.

15. TYPES OF CONSUMERS Vore= to eat Herbivore – only eat plants
Carnivores – only eat meat
Omnivores – eat BOTH plants and meat
Detritovore- breaks down decaying organisms

16. Name the Consumer and Type of Consumer!
Which organism is the Producer?
Primary Consumer?
Secondary Consumer?
Tertiary Consumer?

17. ENERGY PYRAMID
Trophic level is each level in a food chain.
Less energy as you rise to the top
1 J
10 J
100 J

18. Student, Which organism has the most energy?
Student, What is the relationship between the goat and the jackal?
Student, What would happen to the mouse population if the owl, rabbit and snake population increased?
Student, What would happen to the snake population if the Kites decreased?

19. What do you think has more energy, a plant or a wolf? Explain.
Notebook Output
What do you think has more energy, a plant or a wolf? Explain.

20. CREATE YOUR OWN FOOD WEB!
When Mr. Legion says go:
I will have ten minutes to create a food web based off scenarios at my ASSIGNED lab table with my lab group
I will have markers/ poster paper at my lab table
I will bring my notes and pen/pencil
I will speak in professional voices
I will work with MY particular lab group only
