talk to your doctor about the risks and benefits of taking naproxen if you are 65 years of age or older.

An autotrophic (food-making) organism at the base of a food chain or food web that obtains all of its energy from the nonliving environment. Examples of primary producers include plants, algae, and some types of bacteria.
Primary producers, also called autotrophs, are organisms that can produce their own food. Most autotrophs lie at the bottom of the food chain, serving as food sources for animals farther up the line. Primary producers are self-sufficient when it comes to meals: they produce their own food using light, carbon dioxide, water and sometimes other chemicals too.
