The type of ecological interaction that best fits this description is mutualism.
Step-by-step explanation:
The type of ecological interaction that best fits this description is mutualism.
Some plants, like legumes, have nodules on their roots that provide a safe growth chamber for nitrogen-fixing bacteria. In this mutualistic relationship, the bacteria obtain carbon compounds from the plant through photosynthesis and a protected habitat, while the plant benefits from the nitrogen fixed by the bacteria, which can be used for growth and development.
