1. In the boxes below take notes on the role of each life process.
Movement
Reproduction
Organisms can move parts of its
structure. Example: running
Produce similar offspring.
Stimulus and Response
Organisms react to a change in their
environment.
Excretion
Nutrition/Food is processed or digested
and waste products are removed. Ex.
Breathing out CO2 or going to the
bathroom.
Growth and Repair
Nutrition
Organisms need to ingest or make food
to provide the materials for growth,
repair, and energy.
Respiration
Organisms exchange gasses to generate
energy.
Organisms grow and develop into their
adult form.
