The primarily use of coal is mostly used for electricity generation, steel production, cement manufacturing, and as liquid fuel.
Advantages: it helps produce electricity, coal energy is affordable energy source because coal's stable price compared to other fuels sources, coal is easy to burn, coal produces high energy upon combustion, coal energy is inexpensive, coal is abundant, coal energy is a reliable energy source.
Disadvantages: coal energy produces large amount of carbon dioxide which leads to global warming and climate change, the burning of coal is not environmental friendly because it produces harmful byproducts and gas emission such as sulfur dioxide, carbon dioxide and nitrogen oxide that causes pollution to the environment including acid rain, coal energy is nonrenewable energy source, coal is fast depleting because we dont consume too much of it, coal mining ruins the environment and puts the lives or people especially the coal miners in danger. <span />
The answer is splitting of water molecules. This happens during the light stage of photosynthesis where light energy from the sun is absorbed by chlorophyll is used to split water molecules into hydrogen ions and oxygen. This process is called photolysis. The hydrogen ions joins the dark stage or the light independent stage, while oxygen gas is either released to the atmosphere or used for cellular respiration.

Initially, it pushes out its pseudopodia so that it can encircle the food. After this, it engulfs the food, thus forming a bag-like structure called food vacuole. The process is known as “phagocytosis”. ... Well, the excess food gets stored in the form of glycogen as well as lipids.
