<h3>
What is Organ donation?</h3>
Organ donation is the process by which a person knowingly consents to having one of their own organs legally removed and transplanted into someone else, either while they are still alive or after they have passed away with the consent of their family.
Donations can be made for medical research or, more frequently, for the transplantation of healthy organs and tissues into other people.
The kidneys, heart, liver, pancreas, intestines, lungs, bones, bone marrow, skin, and corneas are among the organs that are frequently transplanted. While some organs and tissues, such as a kidney or a portion of the liver, pancreas, lungs, or intestines, can be donated by living donors, the majority of donations take place after the donor has passed away.

Answer:
The food chain describes who eats whom in the wild. Every living thing—from one-celled algaeto giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.
For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit. When the fox dies, bacteria break down its body, returning it to the soil where it provides nutrients for plants like grass.
Of course, many different animals eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web.
