The fate of 14C-labelled compounds was determined by quantifying the relative amounts of 14C absorbed by plants, incorporated into soil, taken up into microbial biomass and respired by soil organisms.
The main benefit for the fungus is constant access to a supply of carbohydrates produced by the plant's photosynthesis, while the plant benefits from an enhanced supply of mineral nutrients from the soil, taken up by the hyphae of the fungus.
(1991) showed that under specific conditions bacteria and fungi cells isolated from a soil took up iodine, though they acknowledged that this did not resolve whether microbes may have exerted an indirect effect on iodine sorption, by their action of degrading OM under oxic conditions.
The hyphae (thread-like structures that are part of the body of the fungi) spread through the soil, taking up nutrients such as phosphorus and absorbing water, and transporting them to the plant root, and in return the fungi receive sugars from the plant.
It has been documented that organisms inhabiting contaminated soils take up pollutants, which can bioaccumulate in the complex food chain [9, 22 24].
Vegetables cultivated in contaminated soils take up heavy metals in large quantities enough to cause potential health risks to the consumers [7 10, 12].
Ocean and soils take up about 5 billion tons of carbon dioxide per year for perspective, deforestation and energy-related emissions add 10 billion but they may be losing that ability as the globe warms.
Plant shoots typically grow against the gravity vector to access light, whereas roots grow downward into the soil to take up water and nutrients.
Cattle that forage on dioxin-contaminated soil can take up and bioaccumulate such contamination, which can then be passed on to the human consumers (Chang et al. 1989).
When grown in polluted soil, plants take up water, nutrients, and heavy metals that may then enter the food chain [ 6].
