Answer
Methane### Explanation: Plants require carbon dioxide, soil nutrients, and oxygen for healthy growth. Carbon dioxide is used by plants during the process of photosynthesis to produce glucose, which is a source of energy. Soil nutrients are essential for plant growth as they provide the necessary minerals and vitamins. Oxygen is used by plants for respiration, a process that releases energy from glucose. On the other hand, methane is not a requirement for plant growth. Although it is a greenhouse gas like carbon dioxide, plants do not use it in any of their biological processes. Therefore, the answer is Methane.
