Term
|
Definition
| Organism that feeds on animal tissue; taxonomically, a member of the order carnivora (Mammalia). |
|
|
Term
|
Definition
| An animal that feeds on both plant and animal matter. |
|
|
Term
|
Definition
| Organism that feeds on dead organic matter; usually applies to detritus-feeding organisms other than bacteria and fungi. |

|
Term
|
Definition
| Substance an organisms requires for normal growth and activity. |
|
|
Term
|
Definition
| Cannot be synthesized by given organisms, must be supplied by the diet. |
|
|
Term
|
Definition
| Maintenance of a nearly constant internal environment in the midst of a varying external environment; more generally, the tendency of a biological system to maintain itself in a state of stable equilibrium. |
|
|
Term
|
Definition
| Organisms who rely on internal (metabolic) heat production to maintain relatively high body temperatures. |
|
|
Term
|
Definition
| Organism whose body temperature is determined primarily by external thermal conditions. |
|
|
Term
|
Definition
| Organism who maintains relatively stable body temperature (an example of homeostasis). |
|
|
Term
|
Definition
| Organism whose body temperature changes in concert with external conditions. |
|
|
Term
|
Definition
| An organism that during part of its life history becomes either endothermic or ectothermic; hibernating endotherms become ectothermic, and foraging insects such as bees become endothermic during periods of activity; they are characterized by rapid, drastic, repeated changes in body temperature. |
|
|
Term
|
Definition
| Temporary great reduction in an animal's respiration, with loss of motion and feeling; reduces energy expenditure in response to some unfavorable environmental condition, such as heat or cold. |
|
|
Term
| Operative Environmental Temperature |
|
Definition
| A technique which integrates the effects of all heat transfer processes into one number. |
|
|
Term
|
Definition
| Range of environmental temperatures within which metabolic rates are minimal. |
|
|
Term
|
Definition
| An anatomical and physiological arrangement by which heat exchange takes place between outgoing warm arterial blood and cool venous blood returning to the body core; important in maintaining temperature homeostasis in many vertebrates. |
