Why Do Herbivores Eat?
Food is any material consumed to supply nutritional support to the organisms. It is the fundamental unit of all life and is essential for life. Food is generally of animal, plant or fungi origin, and normally includes essential nutrients, including proteins, carbohydrates, vitamins, minerals or both, and is eaten to sustain life. The human body needs a wide range of foods to survive; however, it uses only a small proportion of the foods that are available in the diet. Plants are the prime source of food and rely on animals to produce proteins and carbohydrates.
Eating becomes a problem for most people when one has a restricted diet due to physiological or environmental signals. A person with a normal body mass but elevated energy requirements will usually have difficulty controlling their hunger when compared to someone with a very low energy level who consumes a high-calorie diet. The reason for this is that both of these people will consume a lot of food to compensate for the difference in energy intake, leading to long-term starvation. This is also the case when a person suffers from a serious disorder such as diabetes. In these cases, hunger often becomes a factor in the management of symptoms.
To overcome hunger, some people use drugs, while others try to alter their behaviour and circumstances. If you are a drug user, you need to change your behaviour if you want to successfully control your hunger. Drugs do not directly feed the brain stem, but they do stimulate the brain stem to produce a certain amount of neurotransmitters, hormones and chemicals that provide satiety signals that help the person feel full. For drug users, some of the common side effects include headaches, insomnia, nausea, sweating, anxiety and cramps. If you are trying to lose weight, it is recommended to eat only certain times of the day and after exercising for at least an hour.
In addition to being able to control hunger, mammals have the ability to regulate metabolism. Although the metabolism of most mammals is controlled by the nervous system, the brain can also control the rate of burning fat, which results in an increased metabolic rate. As the rate of burning fat increases, so does the rate of eating, resulting in a balanced, normal diet. However, in order to burn fat, the metabolism has to work properly.
Herbivores eat plants to obtain nutrients. They have a very low metabolism, so they have to frequently eat large amounts of food to compensate for slow burning fat. These herbivores also have other important roles, such as the digestion of food, but their main advantage is that they rarely suffer from hunger. Herbivores do not require regular food breaks, although when they do eat, they eat a lot. Herbivores, like most carnivores, also scavenge for food to obtain energy.
Bovine (cow, horse, goat, buffalo, rat, etc.) and avian (bird, duck, chicken, etc.) metabolism is quite different than ours. Mammals and most other mammals have a series of organs or glands (e.g., stomach, intestine, liver, pancreas) that break down food items into simple compounds called amino acids which are then transported through the bloodstream to various destinations such as the muscles to become fuel for movement and digestion. Humans and many other mammals have a series of organs or glands called the large intestine and a series of other small intestines (or large intestine and small intestine) that consume food (or partially digested food) and transport the food back to the colon, where it is excreted as waste.
