What are the 7 characteristics of living organisms
Movement Respiration Sensitivity Growth Reproduction Excretion Nutrition
what is movement
an action by an organism causing a change in position or place
what is respiration
the chemical reactions in cells that break down nutrient molecules and release energy for metabolism
what is sensitivity
the ability to detect and respond to changed in the internal or external environment
what is growth
permanent increase in size and dry mass
what is reproduction
the processes that make more of the same kind of organism
what is excretion
the removal of the waste products of metabolism and substances in excess of requirement
what is nutrition
the taking in of materials for energy growth and development
how can organisms be classified into groups
through the features they share
what are species
group of organisms that can reproduce to produce fertile offspring
what is binomial nomenclature
the system of naming species where the scientific name of an organism is made up of two parts(genus and species)
