The iodine cycle is a biogeochemical cycle that primarily consists of natural [1] and biological processes [3] that exchange iodine through the lithosphere, hydrosphere, and atmosphere. [ 3 ] [ 2 ] Iodine exists in many forms, but in the environment, it generally has an oxidation state of -1, 0, or +5.
Iodine cycle diagram showing how iodine is cycled through the ecosystem, including living organisms. The figures all have units of teragrams (Tg). The figures all have units of teragrams (Tg). Iodine is an essential trace element in biological systems.
A biogeochemical cycle, or more generally a cycle of matter, [1] is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. Major biogeochemical cycles include the carbon cycle, the nitrogen cycle and the water cycle. In each cycle, the chemical element or molecule is ...
Botany is a natural science concerned with the study of plants.The main branches of botany (also referred to as "plant science") are commonly divided into three groups: core topics, concerned with the study of the fundamental natural phenomena and processes of plant life, the classification and description of plant diversity; applied topics which study the ways in which plants may be used for ...
The nutrient cycle is more often used in direct reference to the idea of an intra-system cycle, where an ecosystem functions as a unit. From a practical point, it does not make sense to assess a terrestrial ecosystem by considering the full column of air above it as well as the great depths of Earth below it.
Botany, also called plant science or phytology, is the branch of natural science and biology studying plants, especially their anatomy, taxonomy, and ecology. [1] A botanist, plant scientist or phytologist is a scientist who specialises in this field.
