macronutrient
(noun)
any of the elements required in large amounts by all living things
Examples of macronutrient in the following topics:
-
Essential Nutrients for Plants
- The essential elements can be divided into macronutrients and micronutrients .
- Nutrients that plants require in larger amounts are called macronutrients.
- Hydrogen and oxygen are macronutrients that are part of many organic compounds and also form water.
- Magnesium (Mg) and calcium (Ca) are also important macronutrients.
- In addition to macronutrients, organisms require various elements in small amounts.
-
Energy and Nutrient Requirements for Prokaryotes
- Prokaryotes need a source of energy, a source of carbon, macronutrients, and micronutrients to survive.
- Just a handful of elements are considered macronutrients: carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
- Why are these macronutrients needed in large amounts?
- Other important macronutrients are potassium (K), magnesium (Mg), calcium (Ca), and sodium (Na).
- In addition to these macronutrients, prokaryotes require various metallic elements in small amounts.
-
The Role of Prokaryotes in Ecosystems
- Carbon is one of the most important macronutrients.
- As a macronutrient in nature, it is recycled from organic compounds to ammonia, ammonium ions, nitrate, nitrite, and nitrogen gas by myriad processes, many of which are carried out solely by prokaryotes; they are key to the nitrogen cycle .
-
Nitrogen Fixation: Root and Bacteria Interactions
- Nitrogen is an important macronutrient because it is part of nucleic acids and proteins.
