As the size of an animal increases, the number of cells in it also increases. all the cells need to work as a team to produce energy for the huge animal to carry out various life processes. there are many organs and blood vessels and there is a lot of work to do in a big animal.SO, THE cells slow down and do more work compared to a tiny animal. thus, the heart beats slower in large animals.
