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 other energy not used in photosynthesis is typically lost as heat energy during the process. Heat energy is a byproduct of many chemical reactions, including photosynthesis, and is released into the environment. This waste heat contributes to Earth's overall heat balance.
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.
The other energy not used in photosynthesis is typically lost as heat energy during the process. Heat energy is a byproduct of many chemical reactions, including photosynthesis, and is released into the environment. This waste heat contributes to Earth's overall heat balance.
Reaching to the Converted was created in 1999-08.
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.
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.
Energy reaching producers that is not converted to growth is typically lost as heat through metabolic processes, used for respiration, or allocated to maintenance functions. Some of it may also be used in other biological activities, such as reproduction or defense mechanisms. Additionally, not all energy captured through photosynthesis is converted into biomass, leading to energy being dissipated back into the environment. This loss of energy contributes to the inefficiency of energy transfer within ecosystems.

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.
Radiation from the sun warms the Earth by penetrating the atmosphere and reaching the surface, where it is absorbed and converted into heat. This process, known as the greenhouse effect, traps some of this heat in the atmosphere, leading to an overall increase in global temperatures.
The hepatic portal system basically consists of the hepatic portal artery, responsible for taking the products of digestion from the small intestine to the liver, where they are broken down further, cleaned of any microbes, and sent to all the body cells via the hepatic portal vein.
