What are life process?

WHAT ARE LIFE PROCESSES? The maintenance functions of living organisms must go on even when they are not doing anything particular. Even when we are just sitting in class even if we are just asleep, this maintenance job has to go on The processes which together perform this maintenance job an We processes . Since these maintenance processes are needed to prevent damage and break-down energy is needed for them. This energy comes from outside the body of the mdhadual organism. So there must be a process to transfer a source of energy from outside the body of the organism which we call food, to the inside, a process we commonly call nutrition If the body size of the organisins is to grow, additional raw material wit also be needed from outside. Since life on earth depends on carbon- based molecules most of these food sources are also carbon-based Depending on the complexity of these carbon sources, different organisms can then use different kinds of nutritional processes The outside sourc...

Nutrition in human being?

Various regions are specialised to perform different functions. What happens to the food once it enters our body? We shall discuss this process here. We eat various types of food which has to pass through the same digestive tract, Naturally the food has to be processed to generate particles which are small and of the same texture. This is achieved by crushing the food with our teeth, Since the lining of the canal is soft, the food is also wetted to make its passage smooth. When we eat something we like, our mouth waters. This is actually not only water..but a fluid called saliva secreted by the salivary glands. Another aspect of the food we ingest is its complex nature. If it is to be absorbed from the alimentary canal, it has to be broken into smaller molecules. This is done with the help of biological catalysts called enzyme...

The forest (or grassland) is a habitat Many animals such as lon som elephants deer, en live in forest habitats.
