Question

Photosynthesis is a chemical reaction that occurs in the leaves of plants. But it
requires a special gas, abiotic component from the atmosphere. What is this
substance?
(a) Carbon di-oxide
(b) Chlorophyll
(c) The sun's energy
(d) Oxygen​

Answer 1

Answer:

a. carbon dioxide

In plants, algae, and cyanobacteria, photosynthesis releases oxygen. ... Carbon dioxide is converted into sugars in a process called carbon fixation; photosynthesis captures energy from sunlight to convert carbon dioxide into carbohydrate. Carbon fixation is an endothermic redox reaction.

Answer 2

Answer:

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.
