Answer:
The model that a tree gets its mass from nutrients in the ground is incomplete because it fails to consider other important factors that contribute to a tree's growth. While it is true that trees obtain nutrients from the ground, they also require other essential resources to grow and thrive.
Explanation:
1. Sunlight: Trees undergo photosynthesis, a process that converts sunlight into energy. This energy is used for growth and other metabolic activities. Sunlight is crucial for trees to produce food and support their growth.
2. Carbon dioxide: During photosynthesis, trees absorb carbon dioxide from the atmosphere. They convert this carbon dioxide into carbohydrates, which serve as building blocks for their growth.
3. Water: Trees rely on water to transport nutrients from the ground to various parts of their bodies. Water is absorbed through the roots and transported through specialized tissues called xylem.
4. Oxygen: Like all living organisms, trees require oxygen for respiration. Through respiration, trees convert stored energy into usable forms, allowing them to carry out vital functions for growth and survival.
