1.1 understand how living organisms share the following characteristics: • they require nutrition • they respire • they excrete their waste • they respond to their surroundings • they move • they control their internal conditions • they reproduce • they grow and develop.

All living organisms require the following characteristics in order to survive:

• Movement - organisms move toward things like water and food and they move away from things like predators.

• Respiration - organisms release energy from their food by the process respiration.

• Sensitivity - organisms respond to changes in their environment.

• Control - organisms can control their internal conditions. eg. water and temperature.

• Growth - all organisms grow and develop into their adult form.

• Reproduction - organisms have to produce offspring in order for their species to survive.

• Excretion - organisms have to excrete (remove) waste. eg carbon dioxide and urine.

• Nutrition - organisms need nutrients to provide them with energy and the raw materials for growth and repair. eg. proteins, carbohydrates, vitamins , minerals and fats.
