Answer:

what is a food chain?

Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism

seaweeds -----> crabs ------>herons

step-1: A food chain always starts with a producer This is an organism that makes its own food Most food chains start with a green plant because plants can make their food by photosynthesis

step-2: Second step of a food chain always starts with a omnivore or herbivore  

herbivores

A herbivore is an animal that gets its energy from eating plants and only plants. Omnivores can also eat parts of plants but generally only the fruits and vegetables produced by fruit bearing plants

omnivores

An omnivore is an animal that has the ability to eat and survive on both plant and animal

step-3: Third step of food chain carnivores or omnivores

carnivore

carnivore meaning "meat eater is an animal whose food and energy requirements derive solely from animal tissue or meat

omnivores

An omnivore is an animal that has the ability to eat and survive on both plant and animal

Consider a series of metabolic events during fasting. Within a few days after a fast begins, nitrogen excretion accelerates to a
timurjin [86]

Answer:

A series of events occur, in prolonged fasting; the body undergoes changes and adaptations of its metabolism to continue to meet energy needs and maintain vital functions, despite not receiving food

These changes are divided into three phases according to the elapsed days of fasting and according to the metabolic processes involved.

First phase: main consumption of reserve carbohydrates.

Second phase: main consumption of fats.

Third phase: serious consumption of proteins.

Explanation:

If the fast is prolonged in time, the metabolic processes change in their qualitative and quantitative characteristics, so that the energy products consumed (glucose, free fatty acids and ketone bodies) are modified, their oxidation decreases globally and after the initial depletion of hepatic and muscular glycogen and protein catabolism, the main source of glucose is the liver through gluconeogenesis. The substrates initially come from protein catabolism and lipolysis, but later protein destruction slows down, maximizing lipolysis.

Between the first phase and the second phase of the fast some muscle proteins are lost but not excessively, even with fasts of two or three weeks.

After about 2 weeks of fasting, up to two-thirds of the energy the brain needs is obtained from ketone bodies. These ketone bodies are the breakdown products of fats and are responsible for the typical ketone breath reminiscent of the smell of acid apples; urine also smells like ketone.

In this phase, damage begins to occur in some important organs such as the liver and kidneys. Starting the first week of fasting, acidosis affects the heart's function of the circulation and the brain.

In the third phase of the prolonged fast it happens from 3 weeks, that is, about twenty days without food, although it varies according to the constitution of each person. A peak of muscle protein consumption occurs and a great loss of weight begins to be perceived with great weakness. Edema occurs and albumin concentration in the blood is altered, as a sign of the self-digestion of muscle proteins.

From approximately 30 days of fasting, the state of malnutrition severely affects all body systems. After forty or fifty days the deterioration is noticeable due to physical wear, the person loses his mobility and suffers from unconsciousness. Finally, starvation death can occur from cardiorespiratory arrest or from lack of blood supply to the brain.
