autotrophs An autotroph (from the Greek autos = self and trophe = nutrition) is an organism that produces organic compounds from carbon dioxide as a carbon source, using either light or reactions of inorganic chemical compounds, as a source of energy. An autotroph is known as a producer in a food chain. Plants and other organisms that carry out photosynthesis are phototrophs (or photoautotrophs). Bacteria that utilize the oxidation of inorganic compounds such as hydrogen sulfide, ammonium or ferrous iron as an energy source are chemoautotrophs. Aloha.

Worcestershire Sauce Ingredients. The ingredients listed on a bottle of Worcestershire sauce - at least on the form of the sauce that is available in my local stores in Canada - are malt vinegar, spirit vinegar, water, molasses, sugar, salt, anchovies, tamarind extract, onion, garlic, spice and natural flavour.
An ad for Lea & Perrins' Worcestershire Sauce from 1901. While many brands of Worcestershire sauce are available on the market, Lea and Perrins â a couple of chemists in Worcester â were the first to develop it. They bottled it as Lea & Perrins Worcestershire sauce almost 200 years ago. The recipe developed accidentally. Their first attempt at the stuff was so bad they stored it in the cellar as a failed attempt. Before getting ready to toss it months later, they gave it another taste to discover it had mellowed into a rich umami sauce.
