Biology homework: design a nutritious lunch for parents, and the comrades help. ...
If it's a biology assignment, I think it's probably a pyramid.

1 Bread is the staple food, and cereal is at the bottom of the pyramid.

2 eggs, one or two meats \ Eggs are the penultimate layer of the pyramid.

3 Milk A cup of beans/milk is the second floor of the pyramid.

Fruits and vegetables are on the penultimate floor, but I don't know if I should eat them in the morning, so I didn't write them down.

The grease is not written on it either.

See my resources for details.
