Carbon forms a vast number of compounds, more than any other element, with almost ten million compounds described to date, and yet that number is but a fraction of the number of theoretically possible compounds under standard conditions. For this reason, carbon has often been referred to as the king of the elements.
Plants are important in the carbon cycle because when animals eat  the plants, the energy from the plant is transferred to the animal.  Then, when the animals break down the â¦ food to release energy,  carbon is returned to the air as carbon dioxide or CO2. 10 people found this useful.
