LIFE PROCESSES Looking at living things Living things Although all living things look different from each other, they all have eight things in common. These eight things are called life processes. Something is only alive if it does all eight processes. THE EIGHT LIFE PROCESSES 1 – Transport All living things circulate materials Animals move substances around their bodies. Plants have water move up from the roots to their leaves and food moves from their leaves to their roots. 2 - Regulation All living things are sensitive All living things respond to changes in their environment. Living things notice changes in their surroundings and react to them. They maintain an internal balance called homeostasis. Eg. Plants grow towards the light. Eg. People react to the temperature around them. 3 - Nutrition All living things need nutrition Food is used to provide energy. Green plants make their own food using sunlight. Animals eat plants or other animals. 4 - Excretion All living things get rid of wastes Waste substances must be removed from the body. Plants and animals both need to get rid of waste gas and water. 5 - Respiration All living things respire Plants and animals use the oxygen in the air to turn food into energy. This process occurs on a cellular level. 6 - Growth All living things grow Babies grow into adults. Seedlings grow into plants. 7 - Synthesis All living things synthesize All living organisms create complex substances in their bodies from simpler ones. 8 - Reproduction All living things reproduce Animals have babies. New plants grow from seeds. This life processes also occurs in each organism for repair and renewal. This is the only life process that is not necessary for the survival of the organism.
