- autotrophs
- organisms that are ably to produce their own food
- binominal nomenclature
- identifying an organism by its genus and species name
- asexual reproduction
- reproduction accomplished by a single organism
- osmosis
- the diffusion of water across a selectively permeable membrane
- osmoregulator
- an organism that regulates its internal concentration of salts
- respiration
- the process by which food is converted into useable energy for life functions
- sexual reproduction
- reproduction that involves that union of gametes from two organisms:a male and a female
- homeotherm
- an animal that maintains a controlled internal body temperature using its own heating and cooling mechanisms
- ectotherm
- an organism whose body temperature is controlled by its surrounding environment
- osmoconformer
- an organism that allows its internal concentration of salts to change in order to match the external concentration of salts in the surrounding water
- photosynthesis
- the process by which an organism uses the energy from the sun to produce its own food
- diffusion
- the movement of molecules from an area of high concentration to an area of low concentration
- heterotrophs
- organisms that connot make their own food and must obtain it from other organisms
- homeostasis
- the tendency of living orgainisms to control or regulate changes in their internal environment
- poiklotherm
- an organism whose body temperature changes with its surrounding environment
- endotherm
- an animal whose internal body temperature is a result of internal sources of heat
- metabolism
- the process by which a living organism takes energy from its surroundings and uses it to sustain itself, develop, and grow
