How do living organisms produce minerals – for example, for their shells? Researchers have come one step closer to answering this mystery. Many organisms can produce minerals or mineralized tissue. A famous example is the nacre, which is used in jewelry because of its iridescent c...
All living organisms are directly or indirectly dependent on soil. Plants obtain water, minerals from the soil and prepare food for animals. Other organisms that live in water are not totally independent of soil because the plants growing on the soil
It helps us calculate the efficiency of machines and processes by comparing the input work and output heat. It allows us to design devices that can convert waste heat into useful work, such asthermoelectric generators. It enables us to understand how living organisms use metabolic energy to perfo...

What is the role of nitrogen-fixing organisms in the nitrogen cycle? How do legumes fit in? Dead plants contain nitrogen in the form of proteins. These are decomposed by bacteria. Outline how bacteria convert nitrogen in these proteins to a form that...
Nitrogen, an element that is essential for all living cells, makes up about 78 percent of Earth’s atmosphere. However, most organisms cannot make use of this nitrogen until it is converted into ammonia. Until humans invented industrial processes for ammonia synthesis, almost all ammonia...
All living matter absorbs carbon from the atmosphere, including an amount of radioactive carbon-14. It is mostly found in atmospheric carbon dioxide because that is where it is constantly being produced by collisions between nitrogen atoms and cosmic rays. What can carbon-14 dating be used for?
