Food is essential for organisms to obtain energy for growth, repair, and maintenance of their bodies. It provides the necessary nutrients, such as carbohydrates, proteins, fats, vitamins, and minerals, that are required for various biological functions to take place. Without food, organisms would not be able to survive and carry out their life processes.
The three characteristics that show a cell is alive are the ability to reproduce, to grow and develop, and to respond to its environment. Cells must maintain these functions to stay alive and function properly.
Natural Selection is the process of organisms adapting and evolving with their surroundings. The weaker ones who cannot adapt die off while the adapting ones stay alive.
