| Definition | Term |
| small-scale variation in a climate caused by a distinctive substrate, location, or aspect. | |
| Term applied to organisms that tolerate/require high-temperaure environments | |
| dormant state some animals enter during summer; involves reduced metabolic rate | |
| transfer of heat through electromagnetic radiation, mainly infared light | |
| if an organism allocates energy to one function, like growth or reproduction, it reduces the amount of energy available to other functions | |
| state of low metabolic rate and lowered body temperature | |
| organism that relies on internal sources of energy for regulating body temperature | |
| dormant state, involving reduced metabolic rate, that occurs in some animals during winter | |
| | Definition | Term |
| organisms whose body temperature varies directly with environmental temperatures | |
| organism that uses metabolic energy to maintain a relatively constant body temperature | |
| physiological adjustment to change in particular environmental factor | |
| organisms that relies mainly on external sources of energy for regulating body temperature | |
| Process in which the photosynthetic pigments of plants, algae, or bacteria absorb light and transfer their energy to electrons | |
| process by which a liquid changes from liquid phase to gas, as in the change from liquid water to water vapor | |
