2. Living things need energy, water, soil, gases and the correct temperature to survive.
3. Organisms are adapted to the conditions of the environment in which they live.


Name the 7 processes of life.

1. Nutrition (feeding)
2. Excretion
3. Sensitivity to the environment
4. Reproduction
5. Respiration (energy production)
6. Growth
7. Movement


Explain Nutrition as one of the 7 processes of life.

Plants make their own food and animals eat plants or other animals.


Explain Growth as one of the 7 processes of life.

All living things increase in size as they grow into adults.


Explain Reproduction as one of the 7 processes of life.

Living things produce new individuals with the same characteristics as their parents.


Explain Respiration as one of the 7 processes of life.

Living things break down food to produce energy.


Explain Excretion as one of the 7 processes of life.

Waste substances are removed from the body.


Explain Sensitivity to the environment as one of the 7 processes of life.

Living things detect changes or stimuli to the environment and react to them. E.g: You may sneeze to remove dust and germs that enter through you nose.


Explain Movement as one of the 7 processes of life.

Animals move from one place to another to find food and shelter, or to avoid danger. Plants do not move although they can grow towards the light and the petals of a flower can open and close in response to light.
