Only a very small fraction (0.1%) is fixed in photosynthesis. More than half is used for plant respiration and the remaining part is temporarily stored or is shifted to other portions of the plant. This energy captured from the Sun further reduces when we pass to higher trophic levels.

Out of the total solar insolation that reaches the Earth’s surfa...
's atmosphere, approximately 30% is reflected back into space by clouds, atmospheric gases, and the Earth's surface. The remaining 70% is absorbed by the Earth's surface and atmosphere, leading to the warming of the planet. This solar energy is converted into heat and drives the Earth's weather patterns, ocean currents, and the growth of plant life through photosynthesis. The amount of solar insolation that reaches a particular location on the Earth's surface depends on factors such as latitude, time of day, season, and atmospheric conditions.
