Phosphorus

If you were to blend salmon, pork, parmesan cheese, brazil nuts, and pumpkin seeds, you'd create a disgusting fishy little pig patty that was incredibly high in phosphorous. Within biological organisms, phosphorous is involved in the formation of DNA, among other things. Outside of meaty flesh-bags, phosphorous is an important ingredient in fertilizers, matches, and pyrotechnics. Without this chemical element, you wouldn't be able to enjoy a smoke during a Rammstein concert while eating a home-grown tomato.
