In real life you don't label variables as letters, the other answer is wrong. The real answer is something like a drought where apple trees have less nourishment to grow apples, or a heat wave or flash flood. Hope this helps!
a variable is a letter so just be like 13a or something like that
The amount of fruit produced by an apple tree can be affected by various factors, including water availability, soil quality, sunlight, pollination, temperature, pest pressure, and the age of the tree. These elements are essential for healthy growth and can significantly influence apple production outcomes.
