Primary producer = plants (and other photosynthetic organisms)
![Page 10: IV. Ecosystem Ecology A. Energy Flow 1. Food chains 2. Productiion](https://reader036.fdocuments.us/reader036/viewer/2022062323/56815e06550346895dcc52cb/html5/thumbnails/10.jpg)
Primary consumer = herbivore (things that eat producers)
![Page 11: IV. Ecosystem Ecology A. Energy Flow 1. Food chains 2. Productiion](https://reader036.fdocuments.us/reader036/viewer/2022062323/56815e06550346895dcc52cb/html5/thumbnails/11.jpg)
Tertiary consumer = carnivore (animals that eat secondary consumers)
![Page 12: IV. Ecosystem Ecology A. Energy Flow 1. Food chains 2. Productiion](https://reader036.fdocuments.us/reader036/viewer/2022062323/56815e06550346895dcc52cb/html5/thumbnails/12.jpg)
Omnivore = animal that eats from several trophic levels

Detritovore = organisms that eat non-living organic matter
