THE WATER, PHOSPHOR AND SULPHUR CYCLES IN NATURE

THE WATER, PHOSPHOR AND SULPHUR CYCLES IN NATURE As their name suggests, cycles unite plants with animals and human beings constantly. What is the biosphere made up of. Biochemical cycles. The Water cycle. Phosphor is rare but extremely important element. The Phosphor Cycle. Sulphur is an essential nutrient. The Sulphur Cycle. Though we may not realise it, we live our lives closely linked with Nature. Were it not for the continuous renovation of natural cycles, we simply could not survive. - What is the biosphere made up of - Biochemical cycles - Cycles unite plants with animals and human beings constantly - A water molecule we are drinking now might well have formed part of hundreds of different living beings in just a few years. - Sedimentary cycles - All the elements making up living beings renew themselves going through different cycles - The water cycle - Evaporation, condensation an precipitation cycles - Phosphor is rare, but extremely important element. - The Phosphor Cycle - Herbivorous and carnivorous animals and the incorporation of the phosphates - Bacteria break down dead bodies, returning phosphor compounds back to the ground - A percentage of phosphor compounds in soil is transported to the sea by rain - A small percentage of this marine phosphor is returned back to solid land through the excrements of seabirds - Sulphur is an essential nutrient - Sulphur travels from the soil or water to plants and animals - Part of the sulphur contained by the ground is transported to the sea - Mineral carbon and petroleum contain sulphur and their combustion releases sulphur dioxide into the atmosphere where it combines with water vapour and turns into sulphuric acid …. - Were it not for the continuous renovation of natural cycles, we simply could not survive.
