Examples of involuntary action are digestion and breathing.

The food chain that is shown in the food web could be any of the following:
- tree → deer → mountain lion
- grass → rabbit → mountain lion
- grass → rabbit → hawk
- grass → grasshopper → frog → snake → fox
- grass → grasshopper → snake → hawk
- grass → grasshopper → snake → fox → mountain lion
- tree → caterpillar → robin → fox → mountain lion
<h3 /><h3>FURTHER EXPLANATION</h3>
A food chain shows a unidirectional feeding relationship among organisms in an ecosystem. The organisms occupy a certain "place" in the food chain called trophic level. Food chains may have several trophic levels which always begin with the producers.
- Producers are organisms which make their own food. Plants are examples of producers.
- The organisms the directly feed on the plants are called the primary consumers. They are either herbivores or omnivores.
- The organisms that feed on the primary consumers directly are called secondary consumers. Those that feed on the secondary consumers are called tertiary consumers and quaternary consumers feed on tertiary consumers. These are either omnivores or carnivores.
- The apex predator is the animal at the top of the food chain. It is preys on the organisms in the lower trophic levels but nothing preys on it.
A food web, on the other hand, is a series of food chains showing the interdependence of organisms in an ecosystem.

Solar energy is a form of renewable energy, namely energy that cannot be depleted. Other forms of energy like carbon based sources of energy cannot be renewed in a reasonable span after being used (forests take time to grow and oil is created in geological timescales). Joe is trying to deal with the phenomenon of resource depletion. The way he goes about it is making a renewable source of energy more efficient and usable.
