All three are correct — your question includes the independent variable, the dependent variable, and the relationship.
- Independent variable: presence of one species (worms) — you are asking how presence vs. absence (or different densities) of worms affects something else.
- Dependent variable: effect on another species (lima bean plants) — the plant response (growth, health, yield, etc.) is what you would measure.
- Relationship: benefit — the question explicitly asks about a beneficial effect, implying a positive relationship.
Tip: make the variables operational (e.g., worms present vs. absent, or number of worms per pot; measure plant height, biomass, leaf area, or seed count) and include controls to test causation.
