Answer:
Geo thermal : Nuclear reactions
Bio mass : plants
Solar : sun rays
Hydro power : Water
Explanation:
Geothermal energy is also used to directly heat individual buildings and to heat multiple buildings with district heating systems. Hot water near the earth's surface is piped into buildings for heat. A district heating system provides heat for most of the buildings in Reykjavik , Iceland.
The major biomass sources currently used are sugar cane and corn to produce bioethanol , and rapeseed for biodiesel production. Other sources are also used such as sunflower seeds, soybean, canola, peanuts, jatropha , coconut and palm oil for biodiesel, and wheat, sugar beet, sweet sorghum and cassava for bioethanol
Conversion of energy from sunlight into electricity
Hydropower or water power is power derived from the energy of falling or fast-running water, which may be harnessed for useful purposes.
If it cannot avoid it, it just find a mechanism to use oxygen and make it less harmful to itself. This is how the process of cellular respiration may have evolved
Miller Urey experiment mimics the environment we had for earth billion of years ago. They put in inorganic molecules and came out with organic molecules. Other scientist thought that they messed up their experiment, but once other scientists recreated and tested. They saw that Miller and Urey were correct. And that helped them see that the origin of life can come from simple cells.
