NUTRITION
Nutrition is a biochemical and physiological process in which an organism uses food to support its survival. It includes absorption, absorption, similarity, biosynthesis, catabolism and excretion.
The science that studies the physiological process of
nutrition is called the science of nutrition.
Nutrition groups Organisms basically provide themselves with
carbon in one of two ways: autotrophs (the production of organic food) and heterotrophy
(the use of existing carbon dioxide).
Combined with the
source of energy, light (phototrophy) or chemical (chemotrophy), there are four
basic groups of organic matter.
Nutrients are things that a creature uses to survive, grow,
and reproduce.
Nutrients can be synthesized as macronutrients (carbohydrates, dietary fiber, fats, proteins, and water required by several grams) or micronutrients (vitamins and minerals needed in milligrams or microgram quantities).
Human nutrition Human malnutrition is about the provision of essential nutrients from the food needed to support human health and well-being.]
In humans, malnutrition can lead to
degenerative diseases such as blindness, anemia, scabies, premature birth,
childbirth and cretinism,] or life-threatening conditions such as obesity.
Malnutrition can lead to injury in extreme cases, as well as
marusmus deficiency in chronic malnutrition.
Animal food Animal nutrition focuses on the nutritional needs
of animals, often in comparison (or in comparison) with other organisms such as
plants. The diet of carnivore and herbivore varies, with a basic amount of
nitrogen and carbon dioxide depending on your particular diet.
Many herbivores rely on bacterial fermentation to make
digested nutrients from the digestive plants of cellulose, while binding
carnivores have to eat animal meat to get certain vitamins or nutrients that
their bodies cannot digest.
Animals regularly have a higher need for energy compared to
planting. Plant nutrition is the study of the chemical elements required for plant growth. [There are a few principles that
work in plant nutrition.
Some nutrients are directly involved in plant metabolism. However, this principle does not exclude so-called beneficial nutrients, where their presence, although not required, has clear positive effects on plant growth.
Nutrients that can
limit plant growth according to Liebig's minimum low are considered an important plant
component if the plant is not able to complete a complete healthy cycle without
it.
There are 16 essential nutrients for plant soil, except for the three essential elements of carbon and oxygen
that plants get from photosynthetic plants from carbon dioxide in the air, and
hydrogen, found in water.
Plants take the
nutrients in the soil by their roots and air (which mainly includes nitrogen
and oxygen) through their leaves.
Green plants derive their presence from carbohydrates in the
carbon dioxide in the air through the process of photosynthesis.
Carbon and oxygen are absorbed into the air, and some
nutrients are absorbed into the soil.
The absorption of nutrients from the soil is achieved by a
cation rotation, in which the root wool pumps hydrogen ions (H +) into the soil
through proton pumps.
These hydrogen ions
remove the cations attached to poorly charged soil particles so that the
cations are available for root removal. In the leaves, the stomata open to
absorb carbon dioxide and release oxygen.
Carbon dioxide molecules
are used as a source of carbon in photosynthesis.
Although nitrogen is
abundant in Earth's atmosphere, very few plants can actually use this.
Therefore, many plants need a mixture of nitrogen to be present in the soil
where they grow.
This is due to the fact that most of the atmospheric nitrogen
is converted into a nitrogen-fixing process into biologically viable forms in
the soil by bacteria.
Plant nutrition is a difficult subject to fully understand,
partly because of the differences between different plants and even between
different species or people of a particular clone.
Substances present at
low levels can cause symptoms of deficiency, and toxicity can occur at very
high levels. In addition, a deficiency of one element may be expressed as symptoms
of toxicity from another element and vice versa
