Our Biology teacher, Magdalena Ravagnan, asked us to complete this activity from our knowledge which we have been expanding when studying the characteristics of living organisms.
In this picture you can see a a crocodile trying to eat its prey. If you are careful you may be able to catch two of the seven characteristics of life: Movement and Sensitivity. Movement is an action by an organism or part of an organism causing a change of position or place and it can be observed as the crocodile is changing position and place in order to eat its prey. Although the prey is also moving, it is doing it because of sensitivity, as a reaction to the movement of the crocodile and the thought of near death. Sensitivity is the ability to detect or sense stimuli in the internal or external enviornment and to make appropiate responses.
This are the other 5 characteristics and their definition:
Respiration are the chemical reactions in cells that break down nutrient molecules and release energy for metabolism.
Excretion is the removal from organisms of the waste products of metabolism, toxic material and substances in excess of requirements.
Growth is a permanent increase in size and dry mass by an increase in cell number, cell size or both.
Nutrition is the taking in of materials for energy, growth and development.
Reproduction is the process that makes more of the same kind of organisms.
