Heme Iron

Explanation:

Iron from the diet of humans is absorbed through the intestinal mucosa cells, mainly in the duodenum, and is transported in the bloodstream and extracellular fluid bound to a plasma protein called transferrin. Two types of iron are provided by the diet: heme iron and non-heme iron. Heme iron is present in animal foods, such as beef, chicken and fish, and non-heme iron, in addition to being offered by red meat, is also found in cereals and other vegetables.

Heme iron is soluble in small bowel conditions and is easily absorbed into the intestinal mucosa without the interference of chemical and / or dietary factors. For this reason, it is highly absorbed: about 15% of the heme iron ingested by the normal individual and 35% in the one with low iron stores. Heme iron is found in some foods that provide all the amino acids humans need in their diet.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
