Explanation:
The hox gene provides a huge amount of important information about evolution. Hox genes duplication made increased morphological complexity possible triggering the formation of neural crest cells and allowed them to disperse throughout the body, forming a variety of structures. They help lay out the basic body forms of many animals including humans, flies and worms.
Energy is maximum at the level of producers, and then decreases upwards; only 10% of energy is carried on to the next trophic level.
Hence, an energy pyramid diagram for ecosystem studies shows a triangular shape.
