Final answer:
The question is about the different types of iron found in various foods and how they are absorbed by the body.
Step-by-step explanation:
The question is about the different types of iron found in various foods and how they are absorbed by the body. Heme iron is found in meat, poultry, and fish and is easily absorbed, while non-heme iron is found in plant foods and is less readily available for absorption. Heme iron is more efficiently absorbed because it gets transported across intestinal cell membranes and enters the bloodstream, while non-heme iron is not absorbed as well and may require additional factors such as vitamin C to enhance absorption.
