The given question is incomplete question as it lack essential part of question which is :
Ex: Write a hypothesis about the worms and lima bean plants. Be sure to answer the lab question.
Answer:
The correct answer would be : If plants grow in soil with worms, then growth of the lima bean plant will be greater due to worms helps in decomposing organic matter.
Explanation:
In this hypothesis the one species benefits other species in the same ecosystem they both exist. According to the hypothesis presence of the worms helps in the growth of the lima bean plants.
Dependent variable is a variable that depends on change in independent variable. Here the change in the presence of worms affects the growth of the bean plants so, the dependent variable is bean plant and the independent variable is presence of the worms.
Thus, the correct answer is : If plants grow in soil containing worms, then plant growth will be greater, because worms help decompose organic matter
