ABIOTIC |
NON- LVING |
|
|
ABIOTIC
|
Non- Living
|
|
|
ADAPT |
To change behaviour or physiology to cope with the changes in the external or internal environment. Such changes are short- term and are not passed onto offspring |
|
|
ADAPATION |
1. Structure or function of an organism which makes it well suited to its life style and to the environment in which it lives 2. . The process in which the species becomes well suited to its life style and environment |
|
|
BIOTIC |
living |
|
|
CAMBIUM |
Region of rapidly dividing cells (vascular cambium and cork cambium) that produces secondary growth in woody plants
|
|
|
CIRCULATORY ADJUSTMENTS |
Altering of the flow of blood through the skin, which alters the rate of heat exchange |
|
|
CUTICLE |
A layer of non- cellular material on the outer surface of a plant or animal, impermeable to water. E.g. waxy cuticle in plants, chitin- protein layer in arthropods |
|
|
DISTRIBUTION |
Geographic extent; may refer, e.g. to a family, genus, species or particular population of species |
|
|
ENVIROMENT |
Non- living and living surroundings of an organism
|
|
|
EPICORMIC BUD |
Bud that lies under the bark or stem and root of a plant, that are able to sprout and grow after damage to the plant e.g. fire
|
|
|
EVAPORATIVE COOLING |
loss of heat through the evaporation of water e.g. by sweating of panting |
|
|
HALOPHTE |
Plant that has adapted to slaty conditions (saline environment) and which has specialized mechanisms for handling excess salt
|
|
|
HIBERNATION |
In animals, a state of reduced metabolism and controlled lowering of body temperature, such as occurs many cold- climate species in winter. Hibernation reduces the amount of energy required at a time when little food is available |
|
|
HUMUS |
Organic matter formed form the break down of dead plants and animals; makes a dark layer of top soil |
|
|
HYDROPHYTE |
A plant adapted to growing in the water |
|
|
LIGNOTUBER |
A swelling at the base of a stem that is a source of dormate buds; in most eucalyots, aids regeneration after fire
|
|
|
LIMITING FACTOR |
A condition that limits a process, or the abundance and distribution of an organism; for example shortage of light is an environmental factor that limits photosynthesis and plant growth
|
|
|
METABOLIC HEAT |
Internal generated from metabolism the physical and chemical processes of an organism e.g muscle activity; important for main training higher body temperatures in mammals and birds |
|
|
METABOLIC HEAT |
internal generated from metabolism the physical and chemical processes of an organism e.g. muscle activity; important for main- training higher body temperature in mammals and birds |
|
|
MYCORRHIZA |
symbiotic relationship between a soil fungus and a plant (the host). the fungal H Y P H A E are closely associated with the host plants roots. BOTH PARTNERS BENEFIT FROM ASSOCIATION (mutualism) |
|
|
pH |
Acidity or alkalinity. measured by a scale from about 0 - most acid to around 14 most alkaline. neutral pH scale means a tenfold difference in acidity and alkaline. |
|
|
PNEUMATOPHORE |
P N E U M A T O P H O R E aerial root in mangroves that increase the surface area exposed to the air at low tide for oxygen uptake |
|
|
PROTEOID ROOT |
dense clusters of hairy roots near the soil surface; found in plants of the family P R O T E A C E A E e.g. Banksia |
|
|
SALINITY |
increased levels of salt (largely sodium chloride) in water or soil |
|
|
TOLARANCE RANGE |
range of environmental conditions e.g. temperature that an organism can survive in |
|
|
TORPOR |
condition where a vertebrate animal allows its body temperature to drop, and becomes inactive or dormant for a period of time |
|
|
VIVIPARITY |
Sexual reproduction in animals where offspring develop inside the mother and are released as live young e.g. in most mammals; or in plants where seeds germinate while still attached to the parent plant e.g. in some mangroves |
|
|
XEROPHYTE |
a plant that has adapted to arid conditions |
