I believe the answer is b. the bacteria transform nitrogen into useful forms for the plants; the plants provide carbohydrates

Plants need nitrogen from the soil to do photosynthesis and produce carbohydrate. The amount of nitrogen is limited but bacteria can synthesis it, giving the plant ingredients that they need. In return, the plant provide carbohydrate to the bacteria. This is a mutualistic symbiosis because they both gain profit for the cooperation.

Answer is b. b. the bacteria transform nitrogen into useful forms for the plants; the plants provide carbohydrates.

In the root nodules of many legumes, symbiotic nitrogen-fixing bacteria called <em>Rhizobia</em> reside. The relationship between a host legume and the <em>Rhizobia</em> is symbiotic or mutualistic in which both partners get benefit.  Once the <em>Rhizobia</em> have established themselves in the root nodule, the plant provides carbohydrates (food) to the bacteria, and in return the <em>Rhizobia</em> provide ammonia for the formation of amino acids and nucleotides.
