How do food webs show the flow of energy?

Food webs normally start at the bottom and work their way up. Like the plants will be at the bottom, and then each level shows the animals getting bigger while losing energy. You continually lose energy as you work your way up an ecosystem, so normally there are only three or four levels. I hope this helps!

This is what i did 45-5=4040÷4=10so there are 10 white marbles but am not sure is just a question that am not sure
