3. 3. Traditional sources of energy, such as Traditional sources of energy, such as woodwood and and peatpeat, are derived from , are derived from producers such as plants. When organic producers such as plants. When organic materials are burned, the energy stored materials are burned, the energy stored in them is in them is released in the form of heatreleased in the form of heat..

Use the space below to describe how peat Use the space below to describe how peat forms in a bog:forms in a bog:

When plants in a bog die, they fall into the When plants in a bog die, they fall into the water, which has low levels of oxygen. Instead water, which has low levels of oxygen. Instead of decomposing, the plant material builds up of decomposing, the plant material builds up on the bottom of the bog, where it is on the bottom of the bog, where it is compressed by the weight of overlying compressed by the weight of overlying material into a light, spongy material called material into a light, spongy material called peat.peat.
