5. Standard
SB4. Students will assess the dependence of all organisms on one another and the flow of energy and matter within their ecosystems. b. Explain the flow of matter and energy through ecosystems by arranging components of a food chain according to energy flow.

6. Objectives I can differentiate between producers and consumers
I can interpret a food chain and food web.
I can explain the transfer of energy in both a food chain and a food web.

7. How do living things obtain and use energy?
Energy Transfer
How do living things obtain and use energy?

8. What is energy? Energy is the ability to do work
Organisms use energy to eat, breathe, and move.

9. All the energy on Earth originates (comes from) the sun
The Transfer of Energy
All the energy on Earth originates (comes from) the sun

10. Autotrophs produce their own energy using sunlight
Review
What is an autotroph?
Autotrophs produce their own energy using sunlight
What is an heterotroph?
Heterotrophs obtain their energy from eating other organisms

11. Autotrophs obtain energy from the sun through photosynthesis
The Transfer of Energy
Autotrophs obtain energy from the sun through photosynthesis
Autotrophs are also called producers
Why do you think autotrophs are called producers?

12. Heterotrophs obtain energy by eating other living organisms
The Transfer of Energy
Heterotrophs obtain energy by eating other living organisms
Heterotrophs are also called consumers
What does it mean to be a consumer?

13. Think!
1. What is a producer? Are producers and autotrophs the same thing? Explain.
Producers make their own food from photosynthesis and is another name for autotrophs
2. What is an example of a producer?
Grass, trees, and plants are all producers

14. Think!
3. What is a consumer? Are consumers the same thing as heterotrophs? Explain.
Consumers eat other organisms as their energy source and are another name for heterotrophs
4. What is an example of a consumer?
Consumers include humans and all types of heterotrophs

15. What are the different types of Heterotrophs?

16. When you see herbivore think herbs and vegetarian!
Herbivores
Herbivores: only eat autotrophs, such as grass, berries, and other plants.
When you see herbivore think herbs and vegetarian!
Examples: Rabbits, deer, horses, and elephants
Can you think of any more herbivores?

17. Carnivores Carnivores: eat only heterotrophs or other animals
When you see carnivores think meat eater!
Example: Lions, sharks, and snakes

18. Omnivores: eat both plants and animals
Example: Humans, Rats, Mice, and Pigs
Would a vegetarian still be considered an omnivore?

19. Decomposers Decomposers: eats dead or dying animals
Also known as Saprophytes or Scavengers
Example: Bacteria and fungi

20. What type of heterotroph?
Think:
What type of heterotroph?

21. Can eat both plants (autotrophs) and animals (heterotrophs)
Herbivores, Carnivores, Omnivores, or Decomposers
Can eat both plants (autotrophs) and animals (heterotrophs)

22. Herbivores, Carnivores, Omnivores, or Decomposers

23. Can eat only animals (heterotrophs)
Herbivores, Carnivores, Omnivores, or Decomposers
Can eat only animals (heterotrophs)

24. Eats dead or dying organisms
Herbivores, Carnivore, Omnivore, or Decomposer
Eats dead or dying organisms

25. Herbivores, Carnivores, Omnivores, or Decomposers

26. Can eat only plants (autotrophs)
Herbivores, Carnivores, Omnivores, or Decomposers
Can eat only plants (autotrophs)

27. Herbivores, Carnivore, Omnivore, or Decomposer

28. Flow of Matter and Energy in Ecosystems

29. Energy Flow Energy flows (moves) in an ecosystem in the form of matter
Matter - the physical substance that makes up everything (atoms)

30. The arrow shows who eats what or whom.
Food chain: is a model that shows how matter and energy move through an ecosystem
berries
rabbit
Tiger
The arrow shows who eats what or whom.
The arrow points towards the predator and away from the prey

31. Nutrients and energy move from:
Producers
Consumers
Decomposers

32. Think
In the food chain to the right, what is the producer?
Who eats the grass?
Who gets energy from the mouse?

33. In which direction does the energy flow?
What is the producer, consumer, and decomposer in the food chain below?
In which direction does the energy flow?

34. Food Web: made up of multiple food chains
Food webs show all the possible feeding relationships for each organism

35. A food web is more realistic than a food chain because organisms depend on more than one other species for food

36. 1. What does the rabbit eat?
2. What eats the rabbit?
3. What would happen to the mouse, rabbit, and goat if all the plants went extinct? How would this affect the lion?

37. Level 4: Tertiary Consumers (who eat Secondary consumers)
Food Web Levels
Level 4: Tertiary Consumers (who eat Secondary consumers)
Level 3: Secondary Consumers (who eat primary consumers)
Level 2: Primary Consumers (who eat producers)
Level 1: Producers
