<h3><u>Answer;</u></h3>
The above statement is True
The energy in fossil fuels is derived from the energy stored in plant and animal matter.
<h3><u>Explanation;</u></h3>
- Fossil fuels are sources of energy that have developed within the earth over millions of years. Because fossil fuels - oil, natural gas, and coal - take so long to form, they are considered nonrenewable.
- Fossil fuels are a great source of energy because they originate from living things. Plants and trees use sunlight to make food from carbon dioxide and water, using the process called photosynthesis. The energy from the sun gets stored in the plants and transferred to any animal that eats the plants.
