European ships established a ‘triangular’ trading route, bringing goods for trade from Europe to the West coast of Africa, then taking slaves across to the New World, and returning to Europe with agricultural commodities from there.
Animals ingest food containing carbon sources such as carbohydrates, proteins and lipids. (Which they get from plants that have absorbed and converted the carbon dioxide into other energies). They then metabolise these substances to produce waste products. One of these waste products is carbon dioxide which they breathe into the atmosphere. Also animals faeces is broken down by bacteria which give off carbon dioxide as they do so.
