1.) Light energy (the electromagnetic radiation of visible light, like colors are a form of light energy), heat energy (energy transfer through kinetic energy that results in what we perceive as heat), mechanical energy (energy created through the power of an object during a certain position or motion- the swinging of a wrecking ball, for example, provides the wrecking ball with enough mechanical energy to break through a wall), electrical energy (energy carried by active electrons within an electrical conductor, like a phone charger), and chemical energy (energy that is released during a chemical reaction, for example, sticking mentos in a bottle of coke creates enough chemical energy to cause the soda to overflow/explode).
2.) Sunlight (solar energy), wood, oxygen, wind, and fresh water.
3.) Petroleum, coal, natural gas (the kind found in the Earth ), and nuclear power.
4.) Fossil fuels (like petroleum, coal, and natural gas-- nonrenewable).
5.) Around 83.5%

The correct answer is 12%.
The chemical element carbon-14 is a radioactive isotope that has 6 protons and 8 neutrons. Since it can be found in all organic materials, its primary utility is for dating organic specimens.
This is due to the fact that carbon-14 slowly declines year after year when an organism dies, while carbon dioxide has a life span of between 5000 and 30000 years. Although a mathematical function determines how it diminishes, graphics like the one below can help explain the process.
The graph depicting the carbon content of organic materials in fossils that are 17,000 years old shows that carbon-14 makes up around 12% of the total carbon content.
