What methods do they use and how do these methods work?
In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.

But did you know, that other than plants, algae and a few types of bacteria, no other living organism can use sunlight directly as a source of energy?
So without Carbon-dioxide, plants wouldn't make food, and we would have no direct source of energy for our own survival. So, thanks to Carbon and the compounds that it forms, we are here to understand the Carbon cycle.
Going back to our analogy with the cake, each form of Carbon (ingredients) exist in set ratios.
Now remembering that animals can intake Carbon and cannot take in more at death, the ratios that exist at the death of the animal is then the exact as the Earth (the ratios in the cake).
It is an intrinsic part of life on Earth, and its importance cannot be undermined. Humans and animals need Carbon for their metabolism, in the form of carbohydrates.Animals are constantly taking in Carbon, from what they eat or breathe in from the air.However they cannot pick and choose which Carbon they want, they have to take in all forms, Carbon 12, 13, and 14.Carbon is also the key ingredient of fossil fuels, petroleum, is used in Carbon-dating, etc.One can go on and on about the uses and benefits of this important element.
