3. Organisms are adapted to the conditions of the environment in which they live.
Name the 7 processes of life.
1. Nutrition (feeding)
3. Sensitivity to the environment
5. Respiration (energy production)
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.
