Bacteriological contamination - penetration into ecosystem

ecosystem. Pollution by micro-organisms is also called 
bacteriological or microbiological impurity.

EKOLOGIYA
no’maqbul ta’sirlarga bardosh bera olish xususiyati. Yuksak 
B.turlar omon qolishi garovidir, muhit doimo o'zgarib 
borayotgan sharoitda(sh.j.antropogen ta’sir ostida) past B. 
turlaming kamayishi va qirilib ketishiga olib keladi.
Tolerance - capacity of living organisms to suffer from the 
unfavorable environmental impact . High T. is a precondition 
for survival of species; low T. leads to reduction and 
disappearance species in conditions of constant environmental 
change (including anthropogenous).
Biogen m odda - organizmlar hayotiy faoliyati natijasida 
vujudga kelgan kimyoviy birkma (lekin aynan shu vaqtnig 
o’zida ularning jismi tarkibida ham bo’ lmasligi mumkin). 
Biogenic m atter - a chemical compound formed as a result of 
living functions of organisms (but it is not necessarily contained 
in composition of their bodies at present time).
Biogenotsenoz — biogenotsenologiyaning asosiy izlanish obekti. 
B.-vitasferaning elementar bioxorologik tarkibiy birligidir va 
shu 
manoda fatsiya, elementlar landshaft tushunchalarining 
sinonimidir, garchi oxirgilaridan farqli o ’laroq, tirik modda 
tushunchasini ham o’z ichiga qamrab oladi. B.tushunchasi 
ekotizim 
tushunchasiga 
yaqin, 
ammo 
keyingisi 
aniq 
bioxorologik asosga ega emasdir.
Biogeocenosis - a basic object research on biogeocenology. B.- 
an elementary biochorological structural unit of vitasphere and 
in this sense is synonymous to concepts of facies and elementary 
landscape, though unlike the letter ones, it necessarily includes a 
living matter. The concept of B.is close to a concept of 
ecosystem, but the latter is dispossessed of a strict 
biochorological base.
