Organisms with a body temperature depending on environment temperature are: Poikilothermic

 

Organisms with a constant temperature not depending on environment temperature are: Homoeothermic

 



Organisms with a large range tolerance to an ecological factor are called: Eyrobionts

 



Organisms with a narrow range tolerance to temperature are called: Stenobionts

 



Percentage of Kazakhstan's soil that is undergone to desertification: about 70%

Permafrost is: permanently frozen layer of ground over 500 thick.

 



Plants and animals become adapted to life in particular biomes through a process of: evolution by natural selection.

 



Plants in an ecosystem play the following role: synthesize organic substances from inorganic compounds

 



Plants of dry habitats adapted to drought and water shortage are: Xerophytes

 



Poikilothermic are organisms with: a body temperature depending on environment temperature

 



Population growth is exponential when: the birthrate reaches its biotic potential

 



Population growth rate is: individuals number change in a population over specific period of time

 



Primary productivity is the energy contained in the trophic level of: producers

 



Primary succession is the sequential replacement of populations starting: in an area that has not previously supported life, such as bare rock or a sand dune.

 



Real consumption of water by a person per day is: 1500-2000 L/day.

 



Renewable resources include: humus

 



Scientists predict the global average temperature will rise by 2025 and by 2100 to: 10C and 30C, correspondingly

 



Secondary succession is the sequential replacement of populations that occurs in all cases, EXCEPT: secondary Succession - the sequential replacement of population in disrupted habitats that have not been totally stripped of soil and vegetation. ??????????????????????????????????????????????????????????

 



Section of ecology that studies an effect of environmental factors to individual organisms is: Autecology

 



Section of ecology that studies biotic relationships between different species is: Synecology

 



Social ecology is a science about: Interaction and intercommunication between human society and environment.

 



Social environment includes: people relationships, psychological climate, health services, cultural values, standard of life.

 



Species that are localized and may have just one population that inhabit only a small area are called: endemic

 



Statistic characteristic of population is: population number

 



Stenobionts are organisms with: a narrow range tolerance to an ecological factor

 



Structure and functions of biosphere is studied by: global ecology

 



Structure, number and dynamic processes in a population are studied by: Demecology

 



Succession is a process where: a community changes over time

Sunlight failing on the green plant primarily: photosynthesis

 



Surrounding of the individuals in which an organism lives and which affects it is: Environment

 



Sustainable use of natural resources means that they should be: ensured the durability of them for future generations

 



Symbiosis is the close association between different species in the system: Example of this tree-mushroom.
