Question

Which part of the nitrogen cycle takes nitrogen from the soil to make amino acids? question 24 options: primary consumer secondary consumer producers legumes?

Answer 1

I believe, from my understanding, that Producers take up nitrogen to make amino acids.

It must be a producer as they are often plants in the soil, also, legumes do take up nitrogen, but 'fix' it into ammonia (N2 + 8H+ + 8e− → 2NH3 + H2) via Rhizobia bacterium.
