Answer:
oxygen (O2)
Explanation:
During photosynthesis carbon dioxide(CO2) and water (H2O) react with help of the sunlight and produce glucose (main product) and oxygen(O2 ), which is by-product and abiotic factor. O2 is needed for all animals and plants to breathe.

NUCLEAR ENERGY
Every second of every day our Sun converts about 4.2 million metric tons (4,200,000,000 kilograms) of hydrogen into helium using a nuclear <span>fusion </span>process. During this nuclear reaction, a small portion of matter is converted to an enormous amount of energy. It is this output that provides the energy for photosynthesis and for heating our atmosphere and oceans.
In this lesson, you will learn the details of the nuclear fusion process. You will also learn about another important nuclear reaction called fission and some useful applications of it.
OBJECTIVES<span>Describe the process of nuclear fusion.Describe the process of nuclear fission.Identify some applications for nuclear reactions.List positive and negative factors associated with nuclear reactions.</span><span>VOCABULARY</span>
