What is the process by which carbon dioxide and water are converted to carbohydrates?
photosynthesis
Carbohydrates are formed in green plants by photosynthesis, which is the chemical combination, or “fixation”, of carbon dioxide and water by utilization of energy from the absorption of visible light.
What is the process by which autotrophs use sunlight carbon dioxide and water to make glucose?
Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose.
Which process is photosynthesis?
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 is carbon dioxide made into water?
The Sabatier reaction or Sabatier process produces methane and water from a reaction of hydrogen with carbon dioxide at elevated temperatures (optimally 300–400 °C) and pressures (perhaps 3 MPa) in the presence of a nickel catalyst.
How does Sun gets its energy?
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. About half of the radiant energy is absorbed by land and oceans.
How do plants convert sunlight into energy?
The plant can convert harvested sunlight into this chemical energy (ATP). Then, they use the ATP to make a type of “stored fuel” – sugars. They make these sugars (carbohydrates) from carbon dioxide and water.
What happens to carbon dioxide and water during photosynthesis?
This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
How do photosynthetic organisms use energy from sunlight?
Photosynthetic organisms, like plants, use the energy that they “capture” from sunlight to make the fuel that they use to live. This fuel is a type of chemical energy, something we call ATP. The plant can convert harvested sunlight into this chemical energy (ATP). Then, they use the ATP to make a type of “stored fuel” – sugars.
What is the second step of photosynthesis called?
In the second step of photosynthesis, the Calvin Cycle, energy from ATP molecules is used to combine hydrogen from water with the carbon dioxide inside the cells of the leaves. This process, called “carbon fixation,” creates food molecules in the form of sugar (glucose) for the plant.
