If you take too much of a fat-soluble vitamin, it could become toxic. Your body is especially sensitive to too much vitamin A from animal sources (retinol) and too much vitamin D. A balanced diet usually provides enough fat-soluble vitamins.he tables below list the vitamins, what they do in the body (their functions), and their sources in food.
Fossil Fuels and Energy Use. Fossil fuels are natural resources such as coal, oil (including gasoline and diesel fuel) and natural gas. They are formed from the remains of ancient plant and animal life. Fossil fuel burning powers our vehicles and industries, heats and cools our buildings, and runs appliances.It also produces electricity that we use for all sorts of purposes, such as lights and computers.hey are formed from the remains of ancient plant and animal life.

Non-Renewable Energy. Non-renewable fossil fuels (crude oil, natural gas, coal, oil shales and tar sands) currently supply Australia with more than 95 percent of our electrical energy needs. Non-renewable energy is energy produced by burning fossil fuels such as coal. They are non-renewable because there are finite resources of fossil fuels on the planet. If they are continually used, one day they will run out. The Source of Fossil Fuels. Just as plants do today, those living millions of years ago converted the sun's light energy into food (chemical) energy through the process of photosynthesis.
