the Sun Solar Energy
The total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year. In 2002, this was more energy in one hour than the world used in one year. Photosynthesis captures approximately 3,000 EJ per year in biomass. The amount of solar energy reaching the surface of the planet is so vast that in one year it is about twice as much as will ever be obtained from all of the Earth's non-renewable resources of coal, oil, natural gas, and mined uranium combined,
Where is the first step in the flow of energy in an ecosystem when it reaches earth??
Solar energy is fixed by the photoautotrophs Photosynthesis

Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.
Solar energy
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Photosynthesis
The flow of energy in an ecosystem originates from solar energy, which is radiant light and heat from the Sun, and the first step in the flow of energy in an ecosystem when it reaches Earth is photosynthesis, a process used by plants and other organisms to convert light energy into chemical energy.
