  2. Nutrient cycle - Wikipedia

    en.wikipedia.org/wiki/Nutrient_cycle

    A nutrient cycle (or ecological recycling) is the movement and exchange of inorganic and organic matter back into the production of matter. Energy flow is a unidirectional and noncyclic pathway, whereas the movement of mineral nutrients is cyclic.

  3. Ecosystem service - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_service

    Nutrient cycling is the movement of nutrients through an ecosystem by biotic and abiotic processes. [26] The ocean is a vast storage pool for these nutrients, such as carbon, nitrogen and phosphorus. The nutrients are absorbed by the basic organisms of the marine food web and are thus transferred from one organism to the other and from one ...

  4. Ecohydrology - Wikipedia

    en.wikipedia.org/wiki/Ecohydrology

    Nutrient spiraling describes the way biological and physical processes are combined to control nutrient transport or nutrient control. Water travels downstream exchanging nutrients through nutrient rich upwellings and oxygen rich down-wellings. Rather than one continuous or gradual exchange, nutrients cycle in compartments along the river bed.

  5. Nutrition - Wikipedia

    en.wikipedia.org/wiki/Nutrition

    A nutrient cycle is a biogeochemical cycle involving the movement of inorganic matter through a combination of soil, organisms, air or water, where they are exchanged in organic matter. [12] Energy flow is a unidirectional and noncyclic pathway, whereas the movement of mineral nutrients is cyclic.

    By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes. Ecosystems provide a variety of goods and services upon which people depend, and may be part of.

  7. Decomposition - Wikipedia

    en.wikipedia.org/wiki/Decomposition

    Wood decomposition is a complex process involving fungi which transport nutrients to the nutritionally scarce wood from outside environment. [56] Because of this nutritional enrichment, the fauna of saproxylic insects may develop and, in turn, affect dead wood, contributing to decomposition and nutrient cycling in the forest floor. [57]

  9. Energy flow (ecology) - Wikipedia

    en.wikipedia.org/wiki/Energy_flow_(ecology)

    Aquatic primary production is dominated by small, single-celled phytoplankton that are mostly composed of photosynthetic material, providing an efficient source of these nutrients for herbivores. [22] In contrast, multi-cellular terrestrial plants contain many large supporting cellulose structures of high carbon but low nutrient value. [22]
