How do elements get into our body?

The most important structural element, and the reason we are known as carbon-based life forms. About 12 per cent of your body's atoms are carbon. The hydrogen atoms in your body were formed in the Big Bang. All the others were made inside a star long ago and were flung into space by a supernova explosion.

the elements are, Chemists and other researchers have been uncovering their roles in a range of important biological processes. By mass, about 96 percent of our bodies are made of four key elements: oxygen (65 percent), carbon (18.5 percent), hydrogen (9.5 percent) and nitrogen (3.3 percent).

Explanation:

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
