1. Nutrition: The process of obtaining and using food for energy and growth. This includes taking in nutrients, breaking them down, and absorbing them.
2. Respiration: The process of releasing energy from food by breaking down glucose in the presence of oxygen. This results in the production of carbon dioxide and water as waste products.
3. Movement: The ability to change position or location. This can be internal, like the movement of blood within the body, or external, like walking or running.
4. Growth: The process of increasing in size and complexity. This involves the production of new cells and tissues.
5. Excretion: The process of removing waste products from the body. This includes waste from digestion, respiration, and other metabolic processes.
6. Sensitivity: The ability to detect and respond to changes in the environment. This can involve responding to stimuli like light, sound, touch, or changes in temperature.
7. Reproduction: The process of producing offspring. This can be either sexual, involving the combination of genetic material from two parents, or asexual, involving only one parent.
These seven processes are essential for the survival and continuation of all living organisms.
