Scholars have traditionally divided uses of animals, [1] plants, [2] and other living things into two categories: practical use for food [3] and other resources; and symbolic use such as in art [4] and religion. [5]
Standing water is a type of freshwater habitat that mainly consists of lakes and ponds. This habitat has limited species diversity because they are isolated from one another and other water systems, unlike running water. [7] Standing water experiences the process of stratification, which is when water is layered due to the oxygen content. [6]
Some rock types containing chlorite, such as chlorite schist, have minor decorative uses or as construction stone. However, chlorite is a common mineral in clay, which has a vast number of uses. [9] Chlorite schist has been used as roofing granules, the mineral granules adhered to asphalt composition shingles due to the green color.
Limited medical use in drugs such as strontium ranelate. Non-toxic; in humans, it often substitutes for calcium. [11] sulfur: 16: 5: Sulfur is essential and ubiquitous, partly because it is part of the amino acids cysteine and methionine. Many metals that appear as enzyme cofactors are bound by cysteine, and methionine is essential for protein ...
Human interactions with microbes include both practical and symbolic uses of microbes, and negative interactions in the form of human, domestic animal, and crop diseases. Practical use of microbes began in ancient times with fermentation in food processing ; bread , beer and wine have been produced by yeasts from the dawn of civilisation, such ...
The "seed" method uses grains of ground shell from freshwater mussels, and overharvesting for this purpose has endangered several freshwater mussel species in the southeastern United States. [5] The pearl industry is so important in some areas, significant sums of money are spent on monitoring the health of farmed molluscs. [6]
Lake ecosystems can be divided into zones. One common system divides lakes into three zones. The first, the littoral zone, is the shallow zone near the shore. [5] This is where rooted wetland plants occur. The offshore is divided into two further zones, an open water zone and a deep water zone.
For example, "green water" use is evapotranspirational use of soil water that has been provided directly by precipitation; and "green water" has been estimated to account for 94% of global beef cattle production's "water footprint", [90] and on rangeland, as much as 99.5% of the water use associated with beef production is "green water".
