  1. FLOW OF ENERGY IN ECOSYSTEMS Its all about what you eat!

  2. An organism is ….. • Any independent living thing • Can be as small as a single celled bacteria • Or as large as a whale!

  3. Categories of Feeding Relationships • Producers • Consumers • Decomposers • Detritivores • Scavengers They are all depend on each other.

  4. Primary Producers • organisms that use energy to make food . (PLANTS) • Process is photosynthesis • Equation: CO2 + water - C6H12O6 + O2 • Or from chemicals – - Chemosynthesis – uranium, arsenic, sulfur, nitrogen

  5. Autotrophs • Term for primary producers- Auto – a prefix meaning oneself • Trophic- relating to food or nutrition • Can make their own food and use it for energy to power themselves.

  6. Consumers • Consumers need to eat their food to get energy. (ANIMALS)

  7. Types of consumers are • There are THREE types of Consumers • Carnivores • Herbivores • Omnivores. • Scavenger • Detritivor and Decomposer • Its still all about what you eat! • Heterotrophs – • Hetero- other / troph- feeding.

  8. Carnivores only eat meat (other animals)

  9. Herbivores eat only plants.

  10. Omnivores eat both meat (animals) and plants.

  11. Decomposers and Detritivore • Decomposers an organism that chemically break down the cells of dead plants and animals into simpler substances.  • -releases organic nutrients to the ecosystem • Examples: • Mushrooms • Bacteria

  12. Detritivores • an animal that feeds on dead organic material, especially plant detritus. • Similar to decomposers • Examples – fungus, bacteria, worms, many other invertebrates.

  13. What would the world look like without decomposers (bacteria and fungi?

  14. Stop…Review…Check…Turn to your partner and tell them the meaning of each word. Also give two examples of each. • Carnivore: • Herbivore: • Omnivore: • Decomposer • Detritivore

  15. How they relate .

  16. Stop…Review…Check…Turn to your partner and tell them the meaning of each word. Also give two example of each. • Producers: • Consumers: • Decomposers: • Detritivore:

  17. Energy and Biomass Pyramids

  18. On a sheet of note book paper describe the following animals as either a producer, consumer or decomposer. For the consumers, make sure to include if they are a carnivore, herbivore or omnivore. Please use complete sentences! (Ex: A _____ is a ______.) • Bear • Shark • Rabbit • Cherry tree • Mushroom • Human • Tulip (flower) 8. Panther 9. Giraffe 10. Worm

  19. Practice and Create Your Own
