The interaction between worms and lima beans is called? Why is the interdependence of the worms and plants a good example of commensalism?
The correct answer and explanation is:
Correct Answer:
The interaction between worms and lima beans is called commensalism.
Explanation (300 words):
Commensalism is a type of symbiotic relationship between two organisms where one benefits while the other is neither helped nor harmed. In the case of worms and lima beans, the worms benefit from the environment around the lima bean plants, while the plants themselves are largely unaffected by the presence of the worms.
Worms, particularly earthworms, live in the soil and feed on organic matter such as dead leaves and decaying plant material. When lima bean plants grow, they contribute organic matter in the form of fallen leaves, root exudates, and decaying roots, creating a nutrient-rich environment in the soil. The worms use this environment for shelter, food, and breeding grounds. This benefits the worms because it provides them with a stable habitat and ample nutrition.
On the other hand, lima bean plants do not directly gain or lose from the worms’ presence in this interaction. The plants continue to grow and produce beans regardless of whether worms are present or not. In some cases, earthworms can indirectly benefit plants by aerating the soil and increasing nutrient availability, but in strict commensalism, the plant itself does not experience a significant positive or negative effect.
This interdependence is a good example of commensalism because it clearly shows a one-sided benefit. The worms gain shelter and nourishment, while the lima beans remain unaffected. The relationship is stable and non-harmful, illustrating how some species coexist without impacting each other directly but still influencing the ecosystem’s balance.
In ecosystems, commensalism is common and important because it allows diverse species to coexist without direct competition or harm, promoting biodiversity and ecological balance. Thus, the worms and lima beans exemplify a commensal relationship where one species benefits while the other remains neutral.
