cyanobacteria releases oxygen as a byproduct into the atmosphere.
Oxygen
Every photosynthetic organism produce it.Photolysis of water give rise to it
oxygen
carbon dioxide
Because they were the first steps to life on earth
Yes, rubidium is a pure element found in nature. It is an alkali metal and is the 16th most abundant element in the Earth's crust. Rubidium is most commonly obtained as a byproduct of lithium production or extracted from certain minerals.
the carbon source from photosynthesis is CO2 in the atmsphere. Carbon is the second most abundant element in living matter.
No. Photosynthesis involves plants taking carbon dioxide and, using sunlight for energy, forming sugar and oxygen. Radioactive decay involves a single element (no sunlight, no plants) releasing particles and changing (decaying) into a different element.
Oxygen is the element produced after photosynthesis.
No, it is not an element. Photosynthesis is a chemical process mainly found in plants when they use the energy from the sunlight.
The sun provides energy for plants so they can conduct photosynthesis similar to how animals use sugar for energy however the byproduct of photosynthesis would be oxygen and this element is needed to sustain life on Earth.
Helium (or alpha particles)
salt, or waterwater
Glucose is formed by photosynthesis. The other product is oxygen, but that is an element.

Plutonium Could it also include Neptunium? This I believe is also man made.
carbon dioxide

Neptunium is a transuranic element, meaning that it has so many protons that it does not occur in nature. Most commonly Neptunium is a byproduct of nuclear reactions and attempts to create Plutonium (another transuranic element).
One common element is carbon. Anything that comes from the byproduct of a living thing contains carbon.
