The proportion of photosynthetic activity of plants and other photosyn-

thesizers to the respiration of other organisms determines the specific compo-

sition of the Earth's atmosphere, particularly its oxygen level. Global air cur-

rents mix the atmosphere and maintain nearly the same balance of ele-

ments in areas of intense biological activity and areas of slight biological

activity.

Water is also exchanged between the hydrosphere, lithosphere, atmos-

phere and biosphere in regular cycles. The oceans are large tanks, which store

water, ensure thermal and climatic stability, as well as the transport of chemi-

cal elements thanks to large oceanic currents.

9. Mark these statements as true or false (T/F). Prove the true sen-

tences and correct the false ones.

1. The biosphere is sphere of soils and rocks.

2. At the ecosystem and biosphere levels, there is a continual recycling of

carbon, nitrogen, oxygen and other elements, such as phosphorus, cal-

cium, and potassium.

3. The process of photosynthesis releases carbon.

4. Glucose and other sugar molecules are concentrated in nectar and attract

pollinators to aid plants in reproduction.

5. Water and carbon dioxide are the two constituents which cause the

process of cellular respiration.

6. Water cycles between the hydrosphere, lithosphere, atmosphere and bio-

sphere.

10. Find Russian equivalents of the following expressions.

Outer layer; living matter; permanent inhabitants; to extend; amino ac-

ids; solar energy; to alternate; cellular respiration; to regain; global air cur-

rents; to maintain; mammal; intense biological activity; carbon dioxide; to

release; secondary energy source; phosphorus; input; to reach well into.

11. Find odd one out. Explain your choice.

• Population, community, species, ecosystem;

• semisphere, hydrosphere, lithosphere, atmosphere, biosphere;

• phosphorus, calcium, potassium, carbon, nitrogen, mercury, oxygen;

• cellular respiration, photosynthesis, recycling of elements, organic state.
