Ecology also teaches that all life on earth can be viewed as a competition among species for the solar energy captured by green plants and stored in the form of complex carbon molecules. A food chain is a system for passing those calories on to species that lack the pant's unique ability to synthesize them from sunlight.

If we address frankly what is evoked by cheese, I think it becomes clear why so little is said. So what does cheese evoke?
