The answer is macrophages. They either actively invade these leukocytes or are phagocytosed, divide in the cells and cause lysis. The promastigotes that invade these leucocytes are transformed into amastigotes in the macrophages. These amastigotes continue attacking other healthy macrophages while others migrate to the mid gut.
Upon hydrolysis of the molecule of ATP, the products are a molecule of ADP or adenosine diphosphate and an inorganic phosphate molecule, along with substantial energy released upon breaking the chemical bond connecting the high energy containing phosphates together in ATP.
The information that may be shown in an ecological pyramid is the relative amount of energy.
A food pyramid is wider at the bottom, at lower trophic levels, showing that there is a higher amount of energy available to the producers, and this energy reduces as we move up the trophic levels of the ecosystem.
