that requires oxygen

autotroph

organisms that produce
their food

excretion

removal of wastes made during cellular respiration

growth

heterotroph

organims that consume their food

homeostasis

having all life processes in balance, provides a constant internal environment in the organism

metabolism

all of the chemical reactions occurring in an organism

nutrition

obtaining and making use of substances that provide energy and help to carry out other life processes

regulation

using hormones and nerves to maintain homeostasis

cellular respiration

process where organisms release stored energy from glucose into a form the cell can use

synthesis

making complex materials from simple ones ex. photosynthesis

reproduction

process where organisms of the same type are made

assimilation

incorporation of all the materials into an organism's body

transport

absorbing and circulating materials inside an organism

anaerobic

form of cellular respiration that does not require oxygen

asexual reproduction
