• The process by which an organism obtains its food is called nutrition.
• Based on the mode of nutrition plants are classified into autotrophs and heterotrophs.
• The plants which can synthesize their own food are called autotrophic plants.
• Autotrophs are classified into two types, namely, photoautotrophs and chemoautotrophs.
• The organisms which can synthesize food in the presence of light are called photoautotrophs.
All green plants are autotrophs. Plants prepare their own food by a process called photosynthesis. During photosynthesis, light energy is converted into chemical energy. Sunlight, carbon dioxide, water and chlorophyll are essential for the process of photosynthesis. PTR

Summary
Kidneys have bean shaped structure. They are located in the upper abdominal region, on either side of the vertebral column. Kidney is covered by a thin outer membrane called renal capsule. It consists of three components. They are ureter, urinary bladder and urethra. Ureter arises from the renal hilus of kidney. It opens into a muscular sac called urinary bladder. Urinary bladder stores urine. It opens into a tube called urethra.
• Excretion is the process of separating wastes from the body fluids and eliminating them.
• Excretory system is composed of kidneys, ureters, bladder and urethra.
• Kidneys play major role in the separation of urea, mineral salts, toxins and other waste products from the blood.

Summary
The process of elimination of metabolic wastes from the body is called excretion. In humans, kidneys are the excretory organs. Excretory system is comprised of kidneys, ureters, bladder and urethra. Kidneys play an important role in maintaining the chemical composition of
The kidneys of the fetal pig can be located on both sides of the spine behind the abdominal organs. The kidneys’ are a vital part in the process of removing urine from the body. The path that urine takes to exit the body is very specific. First, the urine is in the kidney. Next, the urine goes into the ureters, followed by the bladder and urethra before exiting.
This organs help get rid of the wastes from the body as either urine or
Refusal of Organ Donation After Death Organ donation definition: it takes healthy organs and tissues from one person(the donor) for transplantation into another(the recipient). An organ transplant may save a person's life, or significantly improve their health and quality of life. Main Social Problem: Refusal of many people to donate due to many factors and obstacles. A chronic shortage of organs for transplantation has and continues to be one of the most controversial pressing health issues in many developed countries.
The process of photosynthesis is vital for the survival of most life on Earth. Without photosynthesis plant life would be unable to create its own food and sustain themselves causing them to die. Earth would lack the oxygen and energy that plant life provides. Producers are the main source of energy for living organisms because they can directly absorb light energy and turn it into chemical energy. Animals then eat the plants which give them a portion of that energy.
The main body is broken into three sections. There is the abdomen, thorax,
All organisms use food molecules, like glucose to produce ATP. The production of ATP occurs during cellular respiration. ATP provides the cells with energy that is necessary to produce oxygen. The seeds/plants are autotrophic organisms, which produce their food from the energy that the light provides them. To release the stored energy within the food molecules, the germinated seeds carry out respiration and the release of carbon dioxide.
The digestive system is responsible for chemically and mechanically breaking down food and includes organs such as, mouth, esophagus, stomach, small intestine, rectum, anus, and additional accessory organs. These organs all aid in the breakdown of food. Food is broken down mechanically by chewing and churning in the stomach, and chemically by acidic enzymes in the stomach and in the small intestine which receives enzymes from the pancreas that are specifically designed for the breakdown of nutrients. Once the food and nutrients are broken down, the excretory system removes whatever the body decides is waste by filtering blood in the nephrons of the kidneys and turning it into urine which is then collected in the bladder and removed from the body when the bladder is
photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.
The small intestine begins with the duodenum which has the large responsibility of continuing to break down the food. The jejunum and ileum are
Imagine if you were in need of a transplant and was waiting for the day when you found your donor match. Many recipients are stuck on the waitlist for a donor and sometimes even pass away because the waitlist took too long. To avoid this issue, a few ideas or systems should be considered in order to make the process quicker. Currently organ donations only consist of hair, blood plasma, and sperm and egg. Since removing your kidney is a riskier procedure than donating your hair, receiving money for the process will influence people to donate.
Elimination covers wide ranges of aspect, such as urine, faeces, diarrhoea, emptying a catheter bag, vomiting etc. According to Perry, Peterson, and Potter (2003), normal elimination of the body wastes through the gastrointestinal and genitourinary tracts is a basic function that most people take for granted. Therefore, when either system fail, normal elimination does not take place. Elimination of liquid and solid waste products is normal routine and ordinary, except a change in habits or illness arises. Changes in bowel or bladder may be signs of illness or may be change of habit (drinking or eating).
The answer- plants have developed many important behavioural and physiological methods not shared
The digestive system is located around the stomach area. Along with the digestive system, many other organ systems all work together to create an organism. An example of this would be if a person eats a sandwich and then goes for a run. During the run, the circulatory system helps the body breathe, the muscle system helps the bones move, and all the while the digestive system digests the food. Later on, the excretory system gets rid of the waste, or food that the body can’t use for nourishment.
Below are a couple of ways by which we rely on plants to survive:
