Im going to use a cactus as an example. A cactus is a plant that lives in hot, dry climates, which has needle like leaves to protect itself from animals searching for water. It has a thick waxy curticle to make it hard for an animal's teeth to pierce the plant and to help keep the water in the plant (the heat makes it easier for the plants water to be used up at a quicker pace).
Solar energy is more Natural since it comes from the sun and easier to harness, while chemical energy is Dangerous because it may fail and cause damage.
