Using corn for energy is an example of biomass.
Yes corn is an autotrophic plant. Autotrophic organisms are able to produce their own food using light energy from the sun water and carbon dioxide. Corn is an example of an autotrophic organism because it can make its own food from these sources. It does so by using a process called photosynthesis. During photosynthesis corn takes in carbon dioxide and water and uses the energy of the sun in order to produce glucose which it uses as a source of energy.
Corn produces energy through photosynthesis, where it converts sunlight into chemical energy stored in the form of glucose. This process occurs in the leaves of the corn plant using chlorophyll, water, and carbon dioxide. The stored energy in corn is then used for growth, development, and reproduction.
Our corn field becomes a fund-raising labyrinth, or corn-maze, each October.

Corn plants store energy (glucose) in their thick stems.

There are quite a few limiting factors for using nuclear energy. Nuclear energy is very expensive to produce for example.
Burning firewood is an example of using chemical energy to produce kinetic energy. The chemical energy stored in the wood is released as heat and light through combustion, which can then be harnessed to generate kinetic energy in the form of motion or electricity.
There are quite a few different problems associated with using geothermal energy. Geothermal energy is quite expensive to utilize for example.
Cracked corn is indeed an energy feed source for livestock. Corn is a high-energy feedstuff no matter how it's processed, and should be treated as such.
All non carnivorous plants are autotrophs because they derive their energy from the sun through photosynthesis. They differ from heterotrophs in that they utilise carbon dioxide and not organic carbon sources.
You would get more energy from eating the corn directly. In general, only about 10% of the energy gets passed up the food chain which means that you only get 10% of the energy that was originally contained in the corn by eating the cow that ate the corn.
