Examples of producers:
Grass, trees, and seaweed…etc.  From these examples, you can see that instead of eating others, producers themselves are the ones being eaten.  Therefore, they are at the bottom of every food chain.

We also call producers autotrophs.  The prefix “auto” means “self”, while the suffix “troph” means food.  Together, autotroph means “self-food”, which describes how producers make their own food.  An easy way to remember all the vocabularies is:

“Producer = autotroph =
one who make its own food”
