Red blood cells do not "eat" other cells as they lack the ability to carry out phagocytosis or engulf and digest other cells like white blood cells do. Red blood cells are primarily involved in transporting oxygen throughout the body and do not have the necessary organelles for cellular ingestion.

Iron is a key component in the production of red blood cells because it is necessary for the formation of hemoglobin, the protein that carries oxygen in the blood. Without adequate iron, the body cannot produce enough hemoglobin, leading to a condition called iron deficiency anemia.
Assuming the question is about red blood cells, the nucleus is no where. DNA is not necessary for red blood cells, their only function is to carry oxygen and carbon dioxide for and from cellular respiration, respectively. Since DNA is necessary mostly for cell division, red blood cells don't have it. Instead of dividing they are replaced on a regular basis. Red blood cells are instead manufactured in bone marrow. White blood cells contain their own set of DNA for division.
Yes, red blood cells cannot utilize ketone bodies for energy because they lack the necessary enzymes to metabolize them.

Red blood cells contain hemoglobin. These cells are also known as erythrocytes.
Whole blood is made up of 55% plasma and 45% blood cells. The blood cells come in three different varieties, red (erythrocytes), white (leukocytes), and platelets (thrombocytes). So, red blood cells, when they are living and functioning. already are found in plasma.
As the name says, red blood cells are found in the blood. If there is blood there, there is red blood cells.
red blood cells and white blood cells the red blood cells keep us a live and the white blood cells fight off disease and infection. To complete the answer, the red cells carry oxygen from the lungs to the tissue, etc., cells that need it.
