No, the energy needed for the growth of green plants comes mainly from the energy released by respiration.
The energy converters in cells are chloroplasts and mitochondria. Chloroplasts are unique to plant cells. Chlorophyll in chloroplasts can absorb light energy, convert light energy into chemical energy, convert carbon dioxide and water into organic matter, and store chemical energy in the organic matter it produces.
Mitochondria can use organic matter from cells as fuel, combine this organic matter with oxygen, and convert it to carbon dioxide and water through a complex process. At the same time, they release the chemical energy contained in organic matter. material to be used by cells. Thus, the energy necessary for the growth of green plants comes mainly from synthesized bioenergy.produced by photosynthesis, which is then converted into energy needed for plant growth through respiration.
Plants do not consume too many resources. Instead, they produce resources needed by other organisms. This is why plants are called “producers”. Plants' energy comes from their own photosynthesis and respiration. Through photosynthesis, plants convert sunlight, carbon dioxide and water into glucose and oxygen.
Part of the oxygen produced by plants is used for their own consumption, and part is replenished in the air to produce glucose, part is used for their own consumption, and the rest is used to form cellulose. The cellulose further forms new stems, leaves, roots, etc.
During the process of photosynthesis, although plants consume water and inorganic materials present inn the soil, water will eventually return to nature through transpiration. In addition, plants absorb only a small amount of inorganic matter from the soil, and dead leaves and fallen fruits from plants rot in the soil, which can replenish the earth's organic matter.
The principle of air energy saving is simply to use a small amount of electricity to transfer heat from the air to heat the water, unlike electric water heaters which directly use electric heating resistors to heat the water. Boil water. The heat of the air costs nothing. One of the expenses is the money needed to hire a professional porter (to buy air power), and the other is the money needed to buy food from the porter (the electricity bill) .
Detailed information:
The air source heat pump worksions and the evaporator draws water from the air. It absorbs heat from the ambient thermal energy to evaporate the heat transfer working fluid. After the vapor of the working fluid is compressed by the compressor, the pressure and temperature increase.
When high temperature steam condenses into liquid through a special annular tube condenser permanently bonded to the outer surface of the water storage tank, the released heat is transferred to the water in the water storage tank of the air source heat pump. . The condensed heat transfer fluid returns to the evaporator via the expansion valve, then evaporates again and the cycle repeats.
The heat transfer fluid of the air source heat pump is a special substance. Its boiling point is minus 40°C under normal pressure and its freezing point is less than minus 100°C. This substance is liquid when. it's cold, but it easily evaporates into gas and vice versa.
Inactual operation, the evaporation limit temperature of the heat transfer fluid in the air source heat pump is about minus 20°C, so the ambient temperature of 5°C is also “hot” for such a low temperature. temperature, even The temperature of snow, say 0°C, is still warm in comparison, so some thermal energy can still be exchanged.
