Probably not enough to measure. Although trees themselves fluctuate in temperature according to the weather, very little if any heat is transferred to the ground by the trees themselves. When plants give off water, we call that transpiration .
Water is absorbed by a plant's roots.
The water moves through the plant and can actually come out of the plant through tiny pores on the underside of the plant's leaves. Transpiration is a small part of the water cycle compared to say evaporation of water from the oceans. The sun can give people energy in a couple ways. When sunshine warms your body it is giving you some heat energy through radiation. The most important way the sun gives us energy is through the food we eat.
