primary nutrient deficiency is caused by lack of intake of said nutrient (deficiency is caused by not consuming the nutrient in adequate amounts)
A primary nutritional deficiency is caused by a simple lack of the nutrient in the diet. For instance, cats that are fed strictly fish develop a primary taurine deficiency because the fish don't have enough taurine in them. A secondary nutritional deficiency is caused by another disease process limiting the amount of the nutrient available to the body. For instance, a cow may develop secondary B12 deficiency if it eats too much of certain weeds that have a vitamin B12-destroy enzyme.

The sequence of stages in the development of a nutrient deficiency typically starts with inadequate dietary intake of the nutrient, leading to decreased levels in the body.
