Mr.Paek showed us an example of a food chain like the one above during class, but

his was a lot simpler. He also showed us an example of a food web like the one below and explained how producers are always at the start of a food chain or web because consumers eat the producer for it nutrients.

this is not a great example of a food web because we don't know the material and what are the producers and what are the consumers of this food web.

We did not have any homework unless you didn't do your notes that were due today.
