From what I learned in my science class we would always Put the decomposers at the very bottom but I don't know if that is correct.since a food web is many overlapping food chains that show how energy flows through an ecosystem I think that the producers should be at the very bottom. Sorry
is food broken down when respiration in plants occur?
A food web can be broken down into separate food chains, which illustrate the linear feeding relationships between organisms in an ecosystem. Each food chain shows how energy and nutrients flow from one organism to another, starting from producers and moving up to various levels of consumers. Additionally, food webs can be categorized into different trophic levels, including primary producers, primary consumers, secondary consumers, and so on.
food isn't exactly broken into molecules. molecules are collections of atoms. those would be too small to see. but food is broken down so the nutrients can be gathered. the food is broken down in the stomach, then, the food goes through the intestines where the nutrients and water are gathered
enzymes
When food is broken down the stored energy is in your cells. When the energy is needed, the cells release the energy.

food
In humans, food is most broken down in the stomach where enzymes, bacteria and acids break the food into simpler parts. The food is then passed to the intestines, where the nutrients are absorbed.
Fat reserves in the body can be mobilized and broken down to release energy.
You get energy into your body.
