Why would water move faster through one kind of tree compared to another, and what might that tell us about their life cycle and susceptibility to environmental changes?

Due to the presence of larger vessels.

Explanation:

Due to the presence of larger vessels of hardwoods in the tree, water move faster in that tree as compared to other type of plants. in smaller plants, small vessels are present which able them to move less amount of water as compared to large trees which have large vessels. It tells us that the tree adopted the environmental changes so that's why to overcome the change, they use more water.
