Energy is decreasing by 500 because some of it is turned into heat energy.
Explanation:
when an animal/creature consumes another living thing and or something that has energy it is decrease to a certain amount because some of the energy that the original animal/creature had is turned into heat energy because they use some of the energy for themselves to survive and live.
For example:
A flower is a producer because it produces energy and gets it gets eaten by a deer and some energy gets changed to heat and the other is consumed by the consumer (the deer) and so on.
Oxygen and nutrients from the mother's blood are transferred across the placenta to the fetus through the umbilical cord. This enriched blood flows through the umbilical vein toward the baby's liver. There it moves through a shunt called the ductus venosus. This allows some of the blood to go to the liver.
A small amount of the blood continues on to the lungs. Most of this blood is shunted through the ductus arteriosus to the descending aorta. This blood then enters the umbilical arteries and flows into the placenta. The oxygen rich blood then returns to the fetus via the third vessel in the umbilical cord (umbilical vein). The oxygen rich blood that enters the fetus passes through the fetal liver and enters the right side of the heart.
