Ham Sandwich?!

[west14darrin]

Trace the energy source linking a ham sandwich to the sun.



does anybody know this?

I would think about what the sun does in an essential step in growth of an important substance in bread. Also the ham...where did it come from (and I don't mean ASDA or Tesco!) Before the shops! Have a think about it.

A ham sandwich of just bread and ham is a travesty...

mm...
bread flour crops, that use the energy taken from sun for their living. meanwhile ham meat animals, animals' energy sources is taken from (the other animals) and finally crops [/b]

margerine or butter should be included too

Mayonaise, Mustard, Lettuce, Tomato, Onion, Cheddar Cheese

COME ON PEOPLE!

Anyhow - To the original poster

Sunlight is captured in photosynthesis and converted to stored energy as carbohydrates or lipids and stored in the tissue of a plant.

We grind up plants like wheat and make bread out of it.

Pigs eat plants (pretty much anything they can get) and the energy in the plants they eat is used to fuel their growth and continued activity. The body-mass of any animal is composed of what it eats drinks and breaths. So the ham you eat is there thanks to the plants the pig ate.

Cheese is also an animal product from an herbivore, so you can trace it right back to plants.

So basically it all is traceable back to the sun as a source of energy, although the molecules and atoms may have come from the ground, the air, or food.

Well, if you want to split hairs, some bacteria use alternative sources of energy, such as minerals or extreme temperatures in deep-sea vents. But, compared to the amount of energy being harnessed from sunlight, those are rather insignificant in the scheme of our every-day lives.
