'Zufuhr' (supply/feed) is a noun derived from the verb 'zuführen' (to supply/feed in). The verb is made up of 'zu' (toward) and 'führen' (to lead). So 'die Zufuhr' is the process or result of 'leading something toward' something.
Dem Motor muss ständig neuer Treibstoff zugeführt werden.
The engine must constantly be supplied with new fuel.
To specify what is being supplied, you usually use the preposition 'von' with the dative or a genitive construction. A compound noun is also often formed.
Die Zufuhr von frischer Luft ist in diesem Raum schlecht.
The supply of fresh air in this room is poor.
The word 'Zufuhr' (supply/feed) belongs more to technical and written language. It is often found in technical, medical, or economic texts.

The report analyzes the supply of raw materials for industry.
In the meaning of 'Versorgung' (supply), 'Zufuhr' is often combined with abstract or intangible things. Typical examples are 'die Zufuhr von Energie' (the supply of energy), 'die Sauerstoffzufuhr' (oxygen supply), 'die Nährstoffzufuhr' (nutrient intake/supply), or 'die Wärmezufuhr' (heat supply).

recording / admission / uptake
When talking about nutrients, both words can be connected with the body, but they do not refer to exactly the same process.

Choose „Zufuhr“ for the nutrients entering the body and „Aufnahme“ for the act of taking them up itself.
