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

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
