Living Processes

Movement, Reproduction, Sensitivity, Growth, Respiration, Excretion and Nutrition.

Movement

Where something moves.

Reproduction

All organisms need to reproduce to keep the species going so they do not all die out.

Sensitivity

Organisms need to be aware of their surroundings. This helps them keep out of danger and away from harm, but it also helps us to find food and shelter. We have our five senses which enable us to sense our surroundings. Plants can sense where light is coming from so they can grow towards the light. Microbes can sense where food is in a similar way to the way we can smell food.

Growth

All living things grow and get bigger. From a tiny seed a tree can grow. Even microbes grow.

Respiration

All organisms need energy so they can do things like move and grow. Respiration releases energy from food so we can do things. All organisms need to respire to get energy.

Excretion

All organisms make waste. When we respire we make carbon dioxide gas. This is got rid of when we breathe. When we go to the toilet to urinate we get rid of waste which was in our blood. All living things must get rid of the waste they make. This is called excretion.

Nutrition

All living things need food. Animals must consume (eat) other living things to get food. Plants can make their own food by photosynthesis. They use simple chemicals and the energy in sunlight to make food like sugar. The living animal, Mrs Nerg, and the seven life processes!

There are seven life processes that tell us that animals are alive. To help us remember them we have found a friend to remind you - Mrs Nerg. Although her name sounds a bit strange, the letters in it stand for the life processes - movement, reproduction, sensitivity, nutrition, excretion, respiration and growth.
