Here is a video clip that reviews how evergy flows through an ecosystem and covers nutrient cycling.

Remember the following relationships:

    Producers (Plants; Autotrophs)
    Primary Consumers (Herbivores; Heterotrophs)
    Secondary Consumers (Carnivores; Heterotrophs)
    Tertiary Consumers (Carnivores; Heterotrophs)
    Decomposers (Scavengers or Detritivores; Heterotrophs)

**Remember that Omnivores can be primary, secondary, or tertiary consumers depending on what they are eating**

Keep in mind that energy flows ONE WAY through an ecosystem, while nutrients are RECYCLED.
