Term
| actual evapotranspiration |
|
Definition
| the actual amount of water that is used by and evaporates from a plant community over a given period of time, largely dependent on the available water and the temperature |
|
|
Term
|
Definition
| the series of biochemical reactions that takes place in the stroma of chloroplasts in photosynthetic organisms and results in the first step of carbon fixation in photosynthesis |
|
|
Term
|
Definition
| a form of photosynthesis in which the two chemical parts of photosynthesis are separated in time because CO2 is taken up at night throught the stomata (which are then closed during the day) and fixed to be used later in the day to complete photosynthesis carbon fixation; an adaptation used by desert plants to conserve water |
|
|
Term
|
Definition
| a genetic race of a plant or animal species that is adapted to a specific set of environmental conditions such as temperature or salinity |
|
|
Term
|
Definition
| the particular type of leaf anatomy that characterizes C4 plants; plant veins are encased by thick-walled photosynthetic bundle-sheath cells that are surrounded by thin-walled mesophyll cells |
|
|
Term
|
Definition
| the physiological responses of plants and animals to the length of day |
|
|
Term
| potential evapotranspiration |
|
Definition
| the theoretical depth of water that would evaporate from a standard flat pan over a given period of time if water is not limiting, largely dependent on temperature |
|
|
Term
|
Definition
| plants that cannot survive and grow in the shade of another plant, requiring open habitats for survival |
|

Term
|
Definition
| plants that can live and grow in the shade of other plants |

Term

Definition
Birds, Mammals—control body
temperature—very inefficient with energy use metabolically but efficiency is not everything. but efficiency is not everything |
|
|
Term
|
Definition
| Everybody else—some use behavior to control body temperature but most every organism just lives with the environmental changes very energy efficient but highly dependent upon environmental conditions. |
