8. Ecological (Energy) Pyramid
Omnivores eat anything
Carnivores eat meat
Insectivores eat insects
Herbivores eat plants
Producers make own food
Trophic level = feeding step

9. Heterotroph – organism that obtains food by consuming other living things; aka consumer
Autotroph – organism that is able to capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds, aka producer
