Which of the following is NOT a key element for vine survival?

The key elements for vine survival include sunlight, proximity to water, and carbon dioxide, all of which are essential for photosynthesis and overall vitality. Sunlight provides the energy that vines need to carry out photosynthesis, while water is crucial for nutrient transport and maintaining plant structure. Carbon dioxide is another vital component as it is one of the essential inputs for photosynthesis, allowing vines to produce food.

On the other hand, excess nutrients can actually be detrimental to vine health. While nutrients are necessary for growth and development, an overabundance can lead to issues such as nutrient toxicity, imbalanced growth, and increased susceptibility to diseases. Therefore, while sunlight, water, and carbon dioxide are critical for the survival of vines, excess nutrients do not contribute positively and can pose risks, making it the correct answer for the question.
