While researching a topic, a student has taken the following notes: Certain plants live in a mutually beneficial relationship (symbiosis) with nitrogen-fixing bacteria.One example is plants in the Fabaceae family, commonly called legumes, which exist in harmony with the bacteria that live inside nodules on their roots.From the plants' roots, the bacteria extract sugar that allows them to conduct a process called nitrogen fixation.During nitrogen fixation, the bacteria extract atmospheric nitrogen (N2) and convert it into ammonia, a compound that the plant can metabolize into amino acids, nucleic acids, and chlorophyll, all important to the plant's development.The student wants to make and support a generalization about the relationship between legumes and nitrogen-fixing bacteria. Which choice most effectively uses relevant information from the notes to accomplish this goal?Some bacteria feed on the sugars provided by plant roots in a process called nitrogen fixation. eliminateLegumes derive the nitrogen they need from atmospheric nitrogen converted into ammonia.eliminateLegumes and nitrogen-fixing bacteria have a symbiotic relationship: the bacteria use sugars from the plants' roots to capture nitrogen from the atmosphere, a process which provides important molecules to the plants. eliminateOne example of a relationship between organisms in nature is a symbiosis, wherein both organisms derive something from the relationship and benefit from it.

Solution
The most effective generalization about the relationship between legumes and nitrogen-fixing bacteria, using relevant information from the notes, is: "Legumes and nitrogen-fixing bacteria have a symbiotic relationship: the bacteria use sugars from the plants' roots to capture nitrogen from the atmosphere, a process which provides important molecules to the plants." This statement accurately summarizes the mutual benefits of the relationship, detailing how each organism contributes and benefits.

Nitrogen is an essential part of the proteins and DNA of organisms. Although nitrogen gas makes up about 78% of Earth’s atmosphere, it is unavailable for use by organisms in its gaseous form.
