Answer:
carbon dioxide- burning of fossil fuels
fluorinated gases- industrial processes
methane- production and transport of oil and natural
gas
nitrous oxide- agricultural and industrial activities
Explanation:
Greenhouse gases are gaseous components that induces greenhouse effect. This means that due to their structural ability to trap heat energy in the atmosphere, they contribute to the global warming effect on the Earth. However, this greenhouse gases are produced in large amounts as a result of the day-to-day anthropogenic activities. The following are the greenhouse gases and how they are produced.
Carbondioxide (CO2)- Carbondioxide is the most common and important greenhouse gas. It is generated via natural processes like respiration but also produced when fossil fuels e.g coal, petroleum etc. are burned.
Fluorinated gases- This is another greenhouse gas caused by activities of man. Fluorinated gases are produced in industries during the production of certain products.
Methane- Methane is a gaseous hydrocarbon and the principal constituent of natural gas. Therefore, the production and transportation of oil and natural gases can lead to the escape of methane into the atmosphere.
Nitrous oxide- Nitrous oxide is an oxide of nitrogen. It is mainly produced via agricultural processes such as nitrification and denitrification or use of fertilizers etc. and also industrial actions.
Answer:
LIGHT ENERGY is converted to CHEMICAL ENERGY in the process of PHOTOSYNTHESIS
Explanation:
According to the law of conservation of energy, energy cannot be created nor destroyed but can only be changed from one form to another. This means that no form of energy gets destroyed but only transformed. This is evidently so in so many natural processes including the process of PHOTOSYNTHESIS undergone by plants.
Photosynthesis, which is the way plants obtain their food via sunlight, converts the LIGHT ENERGY of the sun to CHEMICAL ENERGY in glucose produced. Hence, photosynthesis obeys the law of conservation of energy.
