Oxygen

Explanation:

Producer organisms include plants and algae and refer to organisms that are able to produce their own food by synthesizing it from inorganic matter. This is what plants and algae are able to do through the process of photosynthesis.

During photosynthesis, these organisms produce food for themselves and in doing so produce oxygen as a by-product. This is what contributes mostly to the concentration of oxygen in the atmosphere.

im not suree sorry if wrong

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
