Leonardo de Vinci experimented with a fan-driven cooling system. In the Southwest, the Spaniards draped a mesh of cactus fibers or grass over clay water jars ollas. When there was a breeze this would help cool the air. Early Anglo settlers would hang the ollas in a doorway or window to help improve the coolness.
Early settlers also hung wet burlap at the top of wall openings. When electric fans were introduced, wet sheets were put in front of the fan to cool down the air.
This happened about Also in the early s, settlers would make their own crude coolers. Oscar Palmer of Phoenix is credited with the invention of the evaporative cooler. In he built the first drip type evaporative cooler in Arizona.
By , thousands of homemade coolers had appeared in Arizona. Two University of Arizona professors Martin Thornburg and Paul Thornburg circulated mimeographed instructions on how to build and use evaporative coolers. A food chain is a linear, single direction diagram of the feeding relationships between organisms in a specific area.
To simplify, a food chain shows what eats what. A food chain does not give a good overall account of what happens in an ecosystem because it only shows the feeding relationship of just a few organisms in a straight line pattern. A combination of food chains in a multi-linear, multi-directional way is called a food web.

The fish is eaten by both the heron and the alligator. The alligator also eats the raccoon which eats the frog which eats the mosquito.
