Final answer:

Bacteria assist plants in ecosystem sustainability by converting nitrogen through nitrogen fixation in symbiotic relationships with legume plants.


Explanation:

Bacteria help plants sustain ecosystems by converting atmospheric nitrogen into usable compounds, such as ammonia through a process called nitrogen fixation. This essential partnership is exemplified in symbiotic relationships with legume plants, where bacteria like Rhizobium in root nodules provide plants with ammonia, benefiting both parties and enriching the soil's nitrogen content.
