Classify the interaction between worms and lima bean plants:

Most likely: mutualism (facilitation).

Reasoning:
- Typical "worms" in garden/field contexts are earthworms. Earthworms consume organic matter and microbes, and their burrowing and casting activity improves soil structure, aeration, water infiltration and nutrient mineralization. Those changes reliably increase root growth and nutrient availability for plants such as lima beans, so both partners benefit.
- Earthworms themselves benefit from the plant system because plant litter and root exudates provide food and a favorable habitat.

Notes and exceptions:
- If by "worms" you mean root‑feeding nematodes or caterpillar/larval pests that eat roots, that interaction is parasitism/herbivory (the plant is harmed).
- There are also indirect interactions (e.g., worms that reduce pests or change microbial communities) that are best described as facilitation or ecosystem engineering rather than a strict one‑to‑one mutualism.

If you have a particular worm species in mind, tell me which and I’ll classify more precisely.
