Feces, faeces, or fæces (see spelling differences) is a waste product from an animal's digestive tract expelled through the anus (or cloaca) during defecation. The word faeces is the plural of the Latin word fæx meaning "dregs". There is no singular form in the English language, making it a plurale tantum.

Ecology After an animal has digested material, the remains of it is excreted from its body as waste. Though it is lower in energy than the food it came from, feces may still contain a large amount of energy, often 50% of that of the original food.[2] This means that of all food eaten, a significant amount of energy remains for the decomposers of ecosystems. Many organisms feed on feces, from bacteria to fungi to insects such as dung beetles, which can sense odors from long distances.[3] Some may specialize in feces, while others may eat other foods as well. Feces serve not only as a basic food, but also a supplement to the usual diet of some animals. This is known as coprophagia, and occurs in various animal species such as young elephants eating their mother's feces to gain essential gut flora, or by other animals such as monkeys.

Feces are also an important as a signal. Kestrels for instance are able to detect the feces of their prey (which reflect ultraviolet), allowing them to identify areas where there are large numbers of voles, for example. This adaptation is essential in prey detection, as voles are expert at hiding from such predators.[4] Some caterpillars even shoot their feces away from themselves in an explosive burst, helping them to avoid predators taking advantage of the olfactory signal it creates. In a non-predatory example, dominant wildebeest bulls defend territories marked with feces and pheromones produced by scent glands. Within evolutionary biology, signalling theory refers to the scientific theory around how organisms signal their condition to others. ...

Seeds may also be found in feces. Animals which eat fruit are known as frugivores. The advantage in having fruit for a plant is that animals will eat the fruit and unknowingly disperse the seed in doing so. This mode of seed dispersal is highly successful, as seeds dispersed around the base of a plant are unlikely to succeed and are often subject to heavy predation. Provided the seed can withstand the pathway through the digestive system, it is not only likely to be far away from the parent plant, but is even provided with its own fertilizer.

Organisms which subsist on dead organic matter or detritus are known as detritivores, and play an important role in ecosystems by recycling organic matter back into a simpler form which plants and other autotrophs may once again absorb. This cycling of matter is known as the biogeochemical cycle. To maintain nutrients in soil it is therefore important that feces return to the area from which they came, which is not always the case in human society where food may be transported from rural areas to urban populations and then feces disposed of into a river or sea. Detritus may refer to: In geology, detritus is the name for loose fragments of rock that have been worn away by erosion. ...

Human feces -
In humans, defecation may occur (depending on the individual and the circumstances) from once every two or three days to several times a day. Hardening of the feces may cause prolonged interruption in the routine and is called constipation. Human feces (also faeces — see spelling differences), also known as stools, vary significantly in appearance, depending on the state of the whole digestive system, influenced by diet and health. ...
Constipation or irregularity, is a condition of the digestive system where a person (or animal) experiences hard feces that are difficult to egest; it may be extremely painful, and in severe cases (fecal impaction) lead to symptoms of bowel obstruction. ...
Human fecal matter varies significantly in appearance, depending on diet and health. Normally it is semisolid, with a mucus coating. Its brown coloration comes from a combination of bile and bilirubin, which comes from dead red blood cells.

In newborn babies, fecal matter is initially yellow/green after the meconium. This coloration comes from the presence of bile alone. In time, as the body starts expelling bilirubin from dead red blood cells, it acquires its familiar brown appearance, unless the baby is breast feeding, in which case it remains soft, pale yellowish, and not-unpleasantly scented until the baby begins to eat significant amounts of other food.

Throughout the life of an ordinary human, one may experience many types of feces. A "green" stool is from rapid transit of feces through the intestines (or the consumption of certain blue or green food dyes in quantity), and "clay-like" appearance to the feces is the result of a lack of bilirubin.
Bile overload is very rare, and not a health threat. Problems as simple as serious diarrhea can cause blood in one's stool, turning it black. Black stools caused by blood usually indicate a problem in the intestines (the black blood is digested), whereas red streaks of blood in stool are usually caused by bleeding in the rectum or anus.

Food may sometimes make an appearance in the feces. Common undigested foods found in human feces are seeds, nuts, corn and beans, mainly because of their high Dietary fiber content.

Odor
 The molecule hydrogen sulfide contributes to the smell of feces. The distinctive odor of feces is due to bacterial action. Gut flora produce compounds such as indole, skatole, and thiols (sulfur containing compounds), as well as the inorganic gas hydrogen sulfide. These are the same compounds that are responsible for the odor of flatulence. Consumption of foods with spices may result in the spices being undigested and adding to the odor of feces. Certain commercial products exist that claim to reduce the odor of feces[citation needed]. The perceived bad odor of feces has been hypothesized to be a deterrent for humans, as consumption or touching it may result in sickness or infection.[citation needed] Of course, human perception of the odor is a subjective matter; for an animal that eats feces, it might well smell wonderful.

Uses The feces of animals is often used as fertilizer; see manure. Some animal feces, especially those of the camel, bison and cow, is used as fuel when dried out.[6] Animal Dung, besides being used as fuel, is occasionally used as a cement to make adobe mud brick huts [7] or even in throwing sports such as Cow Pat throwing or Camel Dung throwing contests.[8] Spreading manure, an organic fertilizer Fertilizers (also spelled fertilisers) are compounds given to plants to promote growth; they are usually applied either via the soil, for uptake by plant roots, or by foliar feeding, for uptake through leaves. ...
