This tree is dying in the dry environment. What ABIOTIC limiting factor is affect the tree? please help

Trees do not just die, there is always a primary cause, and often contrib uting factors. Trees need adequate quantities of water, heat, light, nutrients, carbon dioxide, oxygen, and other abiotic resources to sustain life, growth, and reproduction. When these factors are deficient or excessive, they cause mortality
