In What Way Do Nitrogen Compounds Differ from Other Minerals

Question

In what way do nitrogen compounds differ from other minerals needed by plants?
A) Only nitrogen can be lost from the soil.
B) Only nitrogen requires the action of bacteria to be made available to plants.
C) Only nitrogen is needed for protein synthesis.
D) Only nitrogen is held by cation exchange capacity in the soil.
E) Only nitrogen can be absorbed by root hairs.

Accepted Answer

Nitrogen compounds differ from other minerals needed by plants in that they require the action of nitrogen-fixing bacteria (such as rhizobia) to be made available to plants. Other minerals can often be found in the soil in their available form and can be taken up by plants directly through root absorption.
