Study Notes
Life Processes: Nutrition, Respiration, and Excretion
Life processes are essential for the maintenance and survival of living organisms. They help organisms adapt to their environment and perform various functions. The three main life processes, which are common to both plants and animals, are nutrition, respiration, and excretion.
Nutrition
Nutrition is the process by which an organism takes food and utilizes it for energy, growth, and repair. There are different modes of nutrition, including:
- Saprohytic nutrition: Organisms obtain food from dead and decaying matter, such as mushrooms, bread mold, yeast, and some bacteria.
- Parasitic nutrition: Organisms obtain food from living organisms, such as cucuta, orchids, ticks, lice, leeches, roundworms, and tapeworms.
- Holozoic nutrition: Organisms incorporate the entire organism of another species into their bodies, such as certain parasites.
Respiration
Respiration is the process by which food is burnt in the cells of the body with the help of oxygen to release energy. This energy is stored in the form of ATP, which is used for various biological processes. Respiration occurs in the mitochondria and involves the exchange of oxygen and carbon dioxide.
Excretion
Excretion is the process by which waste products are removed from the body. It helps get rid of toxic by-products that the body cannot use and maintains the balance of nutrients and waste materials. Excretion is essential for the proper functioning of the body and its overall health.
These life processes, along with others like transportation and reproduction, work together to ensure the survival and well-being of living organisms. Any disturbance in these processes can lead to health issues and negatively impact the functioning of the body.
