Hydrogen and Carbon - as the name suggests! They are made up of just hydrogen and carbon atoms. Hydrocarbons in fossil fuels come from the organic matter of organisms which lived 300 million years ago under conditions of extreme pressure and temperature.
Hydrocarbons contains atoms of Hydrogen, Oxygen and Carbon, other atoms may also be present.

Hydrocarbons end up in the atmosphere when they are burnt
Hydrocarbons. If you're adding Oxygen, it's Sugars.
These compounds are called "hydrocarbons".
Molecules are formed from chemical elements.
They are made of elements
Bread crumbs are hydrocarbons since they come from bread made with wheat.
The elements that hydrocarbons contain are: -Hydrogen -Carbons
I can tell you one thing for certain: hydrocarbons aren't elements. They're made of hydrogen and carbon, both of which are elements themselves.
Hydrocarbons are not elements; rather, they are compounds (e.g. CH4 is methane).
A candle chemically speaking is a mixture, containing substances which are made up of chemical compounds, which in turn are composed of elements. . A candle is made up of a wick- generally cotton (cellulose)- and candle wax which is a mixture of hydrocarbons.

Carbohydrates, Hydrocarbons, or Lipids in Biology.
Products made form petroleum are called hydrocarbons. Petroleum and natural gas are where most hydrocarbons come from. Hydrocarbons are entirely made from crude oils.
All elements are made up of molecules.
