What percentage of energy is converted into chemical energy by photosynthesis?
Energy Incident on a Leaf
15% is reflected. 5% is transmitted through the leaf. 4% is converted to heat energy. 1% is used in photosynthesis.
What percentage of the energy that hits the earth from the sun is converted to chemical energy via photosynthesis?
Most solar energy occurs at wavelengths unsuitable for photosynthesis. Between 98 and 99 percent of solar energy reaching the Earth is reflected from leaves and other surfaces and absorbed by other molecules, which convert it to heat. Thus, only 1 to 2 percent is available to be captured by plants.
How much energy is ultimately converted into chemical energy by photosynthesis?
Photosynthesis converts about 40% of the energy in light into stable chemical energy and loses the balance as heat. This is actually a very efficient process for converting light energy into chemical energy. The best man-made alternative is about 20% efficient.
Does photosynthesis convert into chemical energy?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
How much percentage of solar radiation is used in photosynthesis?
Therefore, the percentage of solar radiation used in photosynthesis is 4%.
What is the percentage of sunlight is captured by plants to convert it into food energy?
Answer: (d) The green plants capture about 1% of the energy of sunlight that falls on their leaves for the process of photosynthesis. This energy is converted into chemical energy as food. At the subsequent level, 10%energy is available.
How many percent of energy obtained from the sun is utilized by the producers?
Through photosynthesis, producers convert solar energy to chemical energy, energy in the chemical bonds of the food. Of all the energy a plant receives from the sun, only about three percent is converted into chemical energy.
What percentage of light is used for photosynthesis?
First, more than half of the incident sunlight is composed of wavelengths too long to be absorbed, and some of the remainder is reflected or lost to the leaves. Consequently, plants can at best absorb only about 34 percent of the incident sunlight.
How does light energy get converted into chemical energy?
Light energy is converted to chemical energy when a photochemically excited special chlorophyll molecule of the photosynthetic reaction center loses an electron, undergoing an oxidation reaction.
