How have trees changed to suit their environment?

Question

how trees change to live in an evironment and thier structure

Answer 1

As trees age, we see distinct changes in their ability to respond to stress (Figure 2). Young trees have a high ratio of photosynthetic (leaves) to non-photosynthetic (woody) tissue. Consequently, for their size, they produce a relatively high amount of energy. Healthy, young trees produce enough energy for growth and abundant storage. They tolerate environmental change and maintenance treatments. In contrast, mature trees have heavier demands on their energy supply. They utilize some energy for growth, but a large percentage is used just to maintain the massive amounts of existing tissues in the trunk, branches and roots. Additional energy is needed to seal wounds that occur from wind breakage, insect attacks and other sources and for the development of reproductive structures. Because of their tighter energy budget, mature trees have very little stored energy for responding to environmental change. In essence, mature, healthy trees are in delicate balance with their environment. The key to preserving this balance, and therefore their health, is to maintain environmental stability around mature trees.
