How do you differentiate between living and non living things? The answer is as simple, that those organisms who have ability to grow, reproduce, create energy that means metabolism such organisms are called living organisms. The organisms which don’t have ability to grow, reproduce, metabolize are called non living organisms. From this concept, we came to know that every living organisms undergo life processes.
Life processes can be defined as, it is a series of events that happen during life such movement, growth, nutrition, digestion, sensation, circulation, respiration, excretion and reproduction. These processes are essential for living organisms.
So these are the characteristics of living organisms, but what about plants ? How do we know that plants are living ?
Yes, we know plants are living organisms because for nutrition they prepare their own food and get water from soil, if they not get water, their leaves soon change the color from green to blackish and soon fall off from tree. So plants are living organisms.
All the activities are needed for living healthy life. The maintenance of these processes is important. If the person intake the proper amount of healthy food that means the person is receiving nutrition and the next process is digestion. The food gives us energy to perform various daily functions. In the digestive system is working properly then the some amount of food will digest, absorbed in the body and remaining food material will be excreted from the body. It is the normal process for living life.
One more important characteristics of living organisms is reproduction. The reproduction can be defined as the biological process of producing offspring from another living organisms, which are biologically similar to their parents.
Let’s start the chapter by giving answers of some questions.

1.) Define life processes.
Answer :-Life processes can be defined as, it is a series of events that happen during life such movement, growth, nutrition, digestion, sensation, circulation, respiration, excretion and reproduction.
2.) What are the characteristic of living organisms ?
Answer :-movement, growth, nutrition, digestion, sensation, circulation, respiration, excretion and reproduction, these are the characteristics of living organisms.
3.) How can you say plants are living organisms ?
Answer :- Yes, we know plants are living organisms because for nutrition they prepare their own food and get water from soil, if they not get water, their leaves soon change the color from green to blackish and soon fall off from tree. So plants are living organisms.
4.) Define reproduction.
Answer :- The reproduction can be defined as the biological process of producing offspring from another living organisms, which are biologically similar to their parents.
5.) Can you explain the daily life processes of organisms ?
Answer:- The maintenance of these processes is important. If the person intake the proper amount of healthy food that means the person is receiving nutrition and the next process is digestion. The food gives us energy to perform various daily functions. In the digestive system is working properly then the some amount of food will digest, absorbed in the body and remaining food material will be excreted from the body. It is the normal process for living life.
Nutrition
Daily we perform various functions such as talking, walking, running, doing exercise. All these functions need energy that we get from food. Intake of proper amount of food and healthy food is very essential to keep your body in working condition. The food is essential for growth, development, maintaining body posture, health of the organs and getting proper nutrients. So nutrients can be defined as the substances which are present in food gives energy, vitamins, required for growth, development and provides nourishment called nutrients. Nutrients include carbohydrate, protein, vitamins etc.
Nutrition can be explained as, intake of all forms of food and nutrients in normal quantity and absorption of the nutrients, so that they can be utilized in the body.
Every living organisms intake different type of food according to their need. Some organisms eat plants, whereas some can prepare their own food material, others eat the animal food. So every organisms intake the food as they need.
