A
The amount of moisture available to the tree
B
falling temperatures
C

D
the genetic or “biological” clock
Explanation: 

Detailed explanation-1: -Without the sun, plants wouldn’t get the necessary food needed to grow, reproduce, and survive. Plants need three basic things to live: sunlight, water, and carbon dioxide. Through a process called photosynthesis, the plants use the energy from the sun to convert carbon dioxide, soil nutrients, and water into food!

Detailed explanation-2: -Trees use energy from the sun to create sugars through a process called photosynthesis and without these sugars as an energy source a tree cannot grow or ultimately survive. A study by Thomas Givnish found that the process of photosynthesis is directly impacted by the amount of sunlight that hits a tree’s leave.

Detailed explanation-3: -All plants require light for photosynthesis, the process within a plant that converts light, oxygen and water into carbohydrates (energy). Plants require this energy in order to grow, bloom and produce seed. Without adequate light, carbohydrates cannot be manufactured, the energy reserves are depleted and plants die.
