Plants use carbon dioxide and sunlight to make their own food and grow. The carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide.

2. Insect activity will begin immediately if a body is left in the open. That is why insect activity can help investigations with determining certain things such as time of death, where the person died and the like.

3. A light meal will digest in about 1-2 hours. Digestion rates can give useful information about when a person had died. Medium meals take about 3-4 hours to digest and heavier meals take about 6 hours.

4. Indicative acts are actions or behaviors that may or may not have taken place before someone dies. Indicative is suggestive, so it may or may have happened.
