Approximately 1-2% of the solar energy reaching Earth is absorbed and converted into chemical energy through photosynthesis. This process primarily occurs in plants, algae, and some bacteria. The remaining solar energy is either reflected back into space, absorbed by the atmosphere and oceans, or used in other ecological processes, such as heating the Earth's surface and driving weather patterns.
The remaining colors of light that are not absorbed by trees are typically reflected or scattered. This is why we perceive leaves as green, as they reflect green light. This process also helps in photosynthesis as certain wavelengths of light are absorbed by the chlorophyll in the leaves.
Radiation directed at Earth can be absorbed or scattered by the atmosphere before reaching the surface. Different types of radiation can interact with particles in the atmosphere, causing them to be reflected, absorbed, or scattered in different directions, preventing them from reaching the Earth's surface in full intensity.
Ozone is the chemical that blocks most of the ultraviolet light from reaching Earth's surface. It is found in the stratosphere and helps protect living organisms from the harmful effects of UV radiation.
Transpiration is essential to photosynthesis because it helps maintain the water flow through the plant, allowing nutrients and water to be transported to the leaves where photosynthesis occurs. It also cools the plant and creates a negative pressure that helps draw water and nutrients from the soil. Without transpiration, photosynthesis would be limited due to a lack of water and nutrients reaching the leaves.

Both small and large amounts of light reaching Earth are absorbed by plants through the process of photosynthesis. Plants use sunlight to convert carbon dioxide and water into glucose, a form of energy that they can use for growth and development. So, all light absorbed by plants is valuable for their survival and functioning.

While a significant portion of the sun's energy reaching Earth is indeed used for photosynthesis by plants and other organisms, not all of the energy is utilized in this way. Some of it is reflected back into space, absorbed by the atmosphere, or contributes to other natural processes like evaporation and weather patterns.
Roughly 30% of the incoming solar energy is reflected back to space by clouds, the atmosphere, and the Earth's surface. Another 20% is absorbed by the atmosphere and clouds before reaching the Earth's surface, leaving only about 50% to be absorbed by the Earth's surface.
Ultraviolet radiation is the solar radiation least absorbed by the layers of the atmosphere before reaching Earth. This is due to the ozone layer, which helps to absorb and block a significant portion of the incoming ultraviolet radiation.
Radiation directed at Earth can be absorbed or scattered by the atmosphere before reaching the surface. Different types of radiation can interact with particles in the atmosphere, causing them to be reflected, absorbed, or scattered in different directions, preventing them from reaching the Earth's surface in full intensity.
as the distance from the plant increases, the rate of photosynthesis decreases - as less light energy is reaching the plant. Energy cannot be created or destroyed, therefore, if more light energy is put into the equation, more glucose and oxygen will be produced and glucose can be used for processes in the plant such as growth and respiration.
Ozone is the chemical that blocks most of the ultraviolet light from reaching Earth's surface. It is found in the stratosphere and helps protect living organisms from the harmful effects of UV radiation.
25% is absorbed by clouds.25% is reflected by clouds.So 50% of the sun's radiation is lost before it reaches earth's surface.See the diagram link below.
They are the blue and red frequencies of visible light. Green is not absorbed much
