Question 10 How does a plant take in nitrogen? O A OB Oc D A plant takes in nitrogen as nitrites (NO₂) that are received directly from other plants. A plant takes in nitrogen as nitrates (NO3) after nitrogen has been transformed by bacteria. A plant takes in nitrogen as atmospheric nitrogen (N₂) captured directly from the atmosphere. A plant takes in nitrogen as ammonium (NH4*) after a decomposing animal has released the ammonium.

Physical and Chemical features

The physical property of a compound could be determined without modifying the originality of the compound. Examples of physical properties are density, hardness, color, boiling, and melting point. The chemical property expresses the ability of a compound to undergo a particular chemical change.
