Answer:
Altogether there are six life processes which predict the condition of life. Important life processes include nutrition, transportation, metabolism, respiration, reproduction, and excretion.

Answer:
the basic processes of life includes organisation, metabolism ,responsiveness ,movements and reproduction in humans who represent the most complex form of life there are additional requirement such as growth differentiation respiration digestion and excretion all of these processes are interrelated.
Explanation:
the photo answer is very large so that I am explaining it in short.
1. Organisation - at all levels of organisational scheme there is a division of labour each component has its own job to perform in cooperation with others even a single cell if it loses is its integrity or organisation will die.
2. metabolism - metabolism is a broad term that include all the chemical reactions that occur in the body and face of metabolism is catabolism and which complex substances are broken down into simpler building blocks and energy is released.
3. responsiveness - responsiveness for irritability is concerned with the detecting changes in the internal or external environment and reacting to that change it is the act of sensing stimulus and responding to it.
4. Movements - there are many types of movement within the body on the cellular level molecules move from one place to another blood moves from one part of the body to another the diaphragm moves with the every breathe the ability of muscle fibres to shorten and thus to produce moment is called contractility.
5. reproduction - for most people reproduction refers to the formation of a new person the birth of a baby in this way life is transmitted from one generation to the next two reproduction of the organism in a broader sense reproduction also refers to the formation of new cells for the replacement and repair of all cells as well as for growth this is cellular reproduction both are essential to the survival of human race.
6. growth - growth refers to an increase in size idhar through an increase in the number of cells or through an increase in the size of each individual cell in order for growth to occur anabolic processes must occur at a faster rate than catabolic processes.
7. differentiation- differentiation is a development process by which an specialised cells change into specialised cells with distinctive structural and functional characteristics through differentiation cells develop into tissues and organs.
8. respiration - respiration refers to all the processes involved in the exchange of Oxygen and Carbon dioxide between the cells and the external element it includes ventilation the diffusion of Oxygen and Carbon dioxide and the transport of gases in the blood cellular respiration deals with the cells utilisation of Oxygen and release of carbon dioxide in the metabolism.
9. digestion - digestion is the process of breaking down complex ingested food into simple molecules that can be absorbed into the blood and utilised by the body.
10. excretion - excretion is the process that removes the best products of digestion and metabolism from the body it gets rid of buy products that the body is unable to use many of which are toxic and incompatible with.
the 10 life processes described above are not enough to ensure the survival of the individual in addition to this processor life depends on certain physical factors from the environment these include water oxygen nutrients heat and pressure.
