energy use
#3 in characteristics of life
all organisms use energy
relates to both nutrition and cellular respiration
nutrition
the process of taking in food and using it for energy, growth, and good health
metabolism
sum of all chemical activity
the metabolic process may be...?
anabolic or catabolic
anabolic
building up
energy is used
catabolic
breaking down
energy is released
autotrophs
Organisms that are able to make their own food
types of autotrophs
photoautotrophs- produces food using light CO2+ H2O
chemoautotrophs- produces food using a chemical reaction
heterotrophs
organisms that get their nutrients by feeding off nutrients produced by others
types of heterotrophs
chemoheterotrophs- breaks down food by using a chemical reaction
photoheterotrophs- breaks down food by using light
homeostasis
steady state condition, stimulus and response
