1. ENERGY

2. Objectives OUR Objectives:
Examine and categorize feeding relationships

3. ENERGY What is the ULTIMATE SOURCE of energy for a MOST ecosystems?
Energy is then transferred within ecosystems from one organism to another.

5. Feeding Relationships
There are 3 main types of feeding relationships
1. Producer - Consumer
2. Predator - Prey
3. Parasite - Host
How do they trap the sun’s energy? Through what process? What is that process similar to in animal cells?

6. Feeding Relationships
Consumer- all heterotrophs: they ingest food containing the sun’s energy
Herbivores
Carnivores
Omnivores
Decomposers
Energy moves up the food chain through the producer/consumer relationship.

7. HETEROTROPH: REMEMBER THE EQUATION FOR CELLULAR RESPIRATION
HETEROTROPH: REMEMBER THE EQUATION FOR CELLULAR RESPIRATION! HETERO = OTHER TROPH = FEEDER

9. Feeding Relationships
Autotroph- all producers (plants), they trap energy from the sun
They are the Bottom of the food chain and necessary for life on earth.
Think Wall-E
How do they trap the sun’s energy? Through what process? What is that process similar to in animal cells?

11. Photoautotroph – use sunlight energy
AUTOTROPHS
SELF FEEDERS:
Photoautotroph – use sunlight energy
Chemoautotroph – use chemicals as energy

12. REMEMBER THE EQUATION FOR PHOTOSYNTHESIS…
AUTOTROPH:
REMEMBER THE EQUATION FOR PHOTOSYNTHESIS…

13. Photo vs Chemo SYNTHESIS

18. Producer or Consumer?

20. VIDEO

21. ?

23. review Autotroph – Makes its own food = PRODUCER
Video – producer VS Consumer
review
Autotroph – Makes its own food = PRODUCER
Chemo and photo
Heterotroph – Eat others = CONSUMER
Consumers and Decomposers
Carnivorous Plants are photoautotrophs and a only a heterotroph to supplement his diet.

25. Herbivore , Carnivore , Omnivore
What are we missing in this category?
Decomposers: scavengers, detritivores and saprotrophs – Eat dead things and are considered Heterotrophs.
Scavengers eat soft tissue
Detritivores eat detritus or organic debris
Saprotrophs eat whatever is left ; absorbs nutrients. Group includes fungi, protozoa and bacteria.

26. Feeding Relationships
Carnivores-eat meat
Predators
Hunt prey
animals for food.
Scavengers are a type of carnivore that eat dead animals, or carrion. Vultures, hyenas, crabs, deep sea fish-talk about distance from the sun and must eat the dead things that sink to the bottom, bottom feeders

27. Feeding Relationships
Omnivores -eat both plants
and animals
Humans and bears are omnivores but a large and important subset of omnivores are the decomposers. They breakdown dead producers and release the energy back into circulation.

28. Feeding Relationships
Herbivores -eat plants
Humans and bears are omnivores but a large and important subset of omnivores are the decomposers. They breakdown dead producers and release the energy back into circulation.

29. Feeding Relationships
Consumer- Decomposers
Scavengers
Detritivores
Saprotrophs
Humans and bears are omnivores but a large and important subset of omnivores are the decomposers. They breakdown dead producers and release the energy back into circulation.

30. Feeding Relationships
Consumer-Scavangers eat soft tissue
Humans and bears are omnivores but a large and important subset of omnivores are the decomposers. They breakdown dead producers and release the energy back into circulation.

31. Feeding Relationships
Consumer-Detritivores eat detritus or organic debris
Humans and bears are omnivores but a large and important subset of omnivores are the decomposers. They breakdown dead producers and release the energy back into circulation.

32. Feeding Relationships
Consumer-Saprotrophs eat whatever is left ;
Breakdown and absorb nutrients
Group includes fungi, protozoa and bacteria.
Humans and bears are omnivores but a large and important subset of omnivores are the decomposers. They breakdown dead producers and release the energy back into circulation.

33. Feeding Relationships
CONSUMERS
Primary (1st) consumers
Eat plants
Herbivores
2.Secondary (2nd), 3.tertiary (3rd) … consumers
Prey animals
Carnivores
Herbivores are the 1st step up the food chain, they eat the producers

42. Homework
Read page , do all questions and graphic organizers along the way, continue to work on vocabulary.
