Today we talked about what an ecosystem is. This video reviews some of our key terms and reviews what an ecosystem is.
Remember our ecological hierarchy (or levels of organization)
Here is a video clip that reviews how evergy flows through an ecosystem and covers nutrient cycling.
Remember the following relationships:
Producers (Plants; Autotrophs)
**Remember that Omnivores can be primary, secondary, or tertiary consumers depending on what they are eating**
Primary Consumers (Herbivores; Heterotrophs)
Secondary Consumers (Carnivores; Heterotrophs)
Tertiary Consumers (Carnivores; Heterotrophs)
Decomposers (Scavengers or Detritivores; Heterotrophs)
Keep in mind that energy flows ONE WAY through an ecosystem, while nutrients are RECYCLED.
