The significant abiotic by-product of photosynthesis is oxygen. The main product of the process is glucose, which the plant uses as food. The general equation for photosynthesis is:
6CO2 (carbon dioxide) + 6H2O (water) = C6H12O6 (glucose) + 6O2 (oxygen)
It can be seen that plants are important to sustain life because they reduce the earth's carbon dioxide, and replace it with oxygen.
Solar energy.
This is because the solar energy arrives and is trapped as radiation and heat.
ALL animals make use of other animals and organisms for food. They are heterotrophic so they have to get energy elsewhere.
ALL animals are capable of motion at some stage of their lives.
Animals developed specialized cells and tissues that are advanced and complex.
And because all animals eat I would assume they all digest the food they ingest. Other than parasites who don't really digest their food.
1.) carbon dioxide
2.) sulfur dioxide
3.) nitrogen oxides
