Carbon Dioxide (CO2) because it is essential to cellular processes that allow plants to thrive and generate oxygen that we can breathe. Nitrogen could also be an example of one gas that's important.
Answer:
Bacteria and Plants use the process of chemosynthesis to create/make food using chemical reactions.
Explanation:
"Autotrophs that perform chemosynthesis do not use energy from the sun to produce food. Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen. ... Bacteria that live in the deep ocean, near hydrothermal vents, also produce food through chemosynthesis."
The answer is D. Since mitchondra is the energy source for the cell, it provides energy. Be sure to reread the lesson. Hope this helped!
