they cannot be manufactured by the organism
Some nutrients are considered essential in the diets of certain animals because they are unable to be manufactured by the organism. Vitamin A is a fat-soluble vitamin.
Blood. However, the delivery is slightly different than the rest of the body. In the CNS the blood filtered by the blood-brain barrier that only allows certain essential nutrients and oxygen to pass through.
release energy from nutrients
Water (H2O), carbon dioxide (CO2) and solar energy.
polysaccharides and simple sugar. Hope that helped :)
Prototrophs are the wild type cells and would be the bacterial cells capable of utilizing certain nutrients or synthesizing certain compounds. Auxotrophs would be the mutant cells that are not capable of utilizing certain nutrients or synthesizing certain compounds. In the example of bacteria capable of utilizing Lactose as a nutrient source, the ability to lactose is denoted by lac+ and the inability to utilize lactose is denoted lac-.Prototrophs = lac+Auxotrophs = lac-
Essential nutrients include minerals, certain vitamins, and select components of proteins and fats
yes,eating only essential nutrients can make us full for a certain meal. It contains fats which is meat. Water, which is good for our body and Vitamins to strengthen our body.
Essential micronutrients include iodine, iron, vitamin A and folate.A nutrient is a substance used in an organism's metabolism which must be taken in from the environment. Non-autotrophic organisms typically acquire nutrients by the ingestion of foods. Methods for nutrient intake vary, with animals and protists having an internal digestive system, while plants digest nutrients externally and then ingested. Organic nutrients include carbohydrates, fats, proteins (or their building blocks, amino acids), and vitamins. Inorganic chemical compounds such as minerals; water and oxygen may also be considered nutrients. A nutrient is essential to an organism if it cannot be synthesized by the organism in sufficient quantities and must be obtained from an external source. Nutrients needed in relatively large quantities are called macronutrients and those needed in relatively small quantities are called micronutrients . Nutrients are frequently categorized as essential or nonessential. Essential nutrients are unable to be synthesized internally (either at all, or in sufficient quantities), and so must be consumed by an organism from its environment. For humans, these include essential fatty acids, essential amino acids, vitamins, and certain dietary minerals. Oxygen and water are also essential for human survival, but are generally not considered "food" when consumed in isolation. Humans can derive energy from a wide variety of fats, carbohydrates, proteins, and ethanol, and can synthesize other needed amnio acids from the essential nutrients. Non - essential nutrients can still have a significant impact on health, whether beneficial or toxic. For example, most dietary fiber is not absorbed by the human digestive tract, but is important in digestion and absorption of otherwise harmful substances. Interest has recently increased in phytochemicals, which include many non - essential nutrients which may have health benefits.
There are certain characteristics that all animals have, which is why they are all considered to be animals, but the variety of animals is enormous, and I would hardly say that all animals are similar.
Plants generally have several sources of food they create sugars during the day from the sun, photosynthesis, other nutrients are taken in via the root system or even through pored in the leaves. Certain plants in areas of poor soil will trap insects or small animals for their nutrients, taking the nutrients from the corpses there are even plants that encourage animals to defecate in a bowl for the nutrients. Nutrients in the soil come from decaying plants and animals and animals waste these are broken down by insects and bacteria in to soil or loam.
There are seven types of nutrients necessary for the function of the human body: 1.) Carbohydrates, 2.) Vitamins, 3.) Fats, 4.) Proteins (along with their building blocks, amino acids), 5.) Minerals, 6.) Water, and 7.) Oxygen. The first four of these nutrients are referred to as "organic nutrients" and the last three are termed "inorganic nutrients."
They're classified as semi permeable because it only allows certain enzymes and nutrients, etc, to get through.
Yes, certain metals are actually essential nutrients - you will die without them. However, if you're asking whether you can eat the blade on your new pair of scissors, I would recommend you don't.

the animals were completely certain of that they are happy.
Desertation it effects certain animals and plants because plants (not including cactus) need water as well as certain animals (not including animals that live in deserts) if they don't get water they die.
