What pigment deficiency can cause anemia?

Hemoglobin is the correct answer because it is the protein in red blood cells responsible for carrying oxygen throughout the body. A deficiency in hemoglobin can lead to various forms of anemia, a condition characterized by a reduced number of red blood cells or a decrease in hemoglobin levels in these cells. When hemoglobin levels drop, the body does not get enough oxygen, which can result in fatigue, weakness, and other symptoms of anemia.

While chlorophyll is important in plants and involved in photosynthesis, it does not have a role in human blood or anemia. Carotene is a pigment found in plants that converts into vitamin A in the body and does not influence blood oxygen levels or lead to anemia. Myoglobin is a protein found in muscle cells that carries and stores oxygen but is not linked to the type of anemia typically discussed in relation to hemoglobin levels in the blood. Thus, the specific deficiency related to anemia in humans is directly tied to hemoglobin.
