Organisms that use an outside energy source like the Sun to make energy-rich molecules are called producers .
Most producers contain chlorophyll (KLOR uh fihl), a chemical that is required for photosynthesis.
Asheville's climate offers milder summer temperatures and a longer growing season than much of the country, allowing us to grow longer, slow growing crops as well as some heat-intolerant northern species.
A food chain is a simple model of the feeding relationships in an ecosystem.
For example, shrubs are food for deer, and deer are food for mountain lions.
Food chains are representatives of the relationships of living organisms in nature. Most consumers feed on multiple species and in turn, are fed upon by multiple other species. For a snake, the prey might be a mouse, a lizard, or a frog, and the predator might be a bird of prey or a badger.
