Ant is eating mesquite tree and other insects what type of energy is this ant consuming

This would be considered a chemical energy. Consuming food, which contains chemical energies, powers the body to be able to move, talk, proceed with other normal functions. As the foods are broken down inside the body, chemical reactions are formed, powering the ant.

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
