Question
True/False Questions: Write True for each true statement and false for each statement that is incorrect. The basic building blocks of all matter are atoms. Atoms do not change as they pass through the various chemical process of nature. Biological growth can be said to be taking atoms of simple molecules that occur in the environment and using them to construct complex organic molecules. The Laws of Thermodynamics show that we can create energy. Most ecosystems use sunlight t as their primary source of energy. Humans obtain large quantities of nitrogen from the atmosphere for agriculture. Ecosystems replenish nutrients by recycling all materials. Energy conversions are always less than 100 percent efficient because some usable energy is lost as heat. A plant photosynthetic rate is independent of light intensity. The natural balance between the processes of nitrogen fixation and denitrification is severely altered by industrial nitrogen fixation. The natural carbon balance is largely maintained by the processes of photosynthesis and respiration. The burning of fossil fuels converts stored organic carbon to biologically active carbon. Approximately 78 percent of the atmosphere is composed of nitrogen gas, a form of nitrogen available to only a few life forms such as nitrogen fixing bacteria. Plants carry out aerobic respiration 24 hours a day but undergo photosynthesis only when light is available. Wind turbines generating electrical power rely on solar energy. When aqueous solution evaporates, the gaseous water is free of solutes. Elements must occur in particular forms to be useful to biological systems. Solar energy is the fundamental determiner of climate. The amount and energy in the universe remains constant. Plants will conduct photosynthesis when light is available but will conduct aerobic respiration all of the time regardless of light availability.Explanation / Answer
1. True
2. False
3. True
4. False. Neither it can be created nor destroyed.just can transfer from one form to another.
5. True. It is the primarily and essentially component of energy.
6. True. Because plants need lot of nitrogen for its growth.
7. True
8. True. As described by carnot heat engine model.
9. False.
10. True. Artificial fertilizers are making agriculture practices to its poorest efficiency, as per capabilities of agricultural land is concerned.
11. True.
12. True, especially partially combustion products.
13. True.
14. False. In night they use oxygen and in night they use carbon dioxide.
15. False. Both have different source of energy.
16. True.
17. True.
18. True. It carries every mode of energy and thus can change any kind of change in climate.
19. True. Total energy is always conserved.
20. False.
