Warm-blooded creatures, like mammals and birds, try to keep the inside of their bodies at a constant temperature. They do this by generating their own heat when they are in a cooler environment, and by cooling themselves when they are in a hotter environment. To generate heat, warm-blooded animals convert the food that they eat into energy. They have to eat a lot of food, compared with cold-blooded animals, to maintain a constant body temperature. Only a small amount of the food that a warm-blooded animal eats is converted into body mass. The rest is used to fuel a constant body temperature.

Answer:
The correct answer will be option- leukocyte.
Explanation:
The granulocytes are the cells which contain secretory granules in its cytoplasm. The granulocytes are a part of the white blood cells or  "leukocytes" which provide immunity to the organism.
The granulocytes are of three types called mainly the neutrophil, basophil, or eosinophil which provide immunity by ingesting the foreign material and digest the invading microbes by the action of enzymes produced by the granules in the cytoplasm.
Thus, option- leukocyte is the correct answer.
