How will this affect competition between chemoautotrophs and photoautotrophs?

Question

The levels of CO2 in the atmosphere continues to increase. How will this affect competition between chemoautotrophs and photoautotrophs?

Answer 1

Chemotrophs are organisms that obtain energy oxidizing chemical molecules in their environments. The chemotroph is in contrast to phototrophs which use solar energy.
Chemoautotrophs (or chemotrophic autotroph), in addition to deriving energy from chemical reactions, synthesize all necessary organic compounds from carbon dioxide. Chemoautotrophs generally only use inorganic energy sources. Most are bacteria that live in hostile environments such as deep sea vents and are the primary producers in those ecosystems. Evolutionary scientists believe that the first organisms to inhabit Earth were chemoautotrophs that produced oxygen as a by-product and later evolved into both aerobic, animal-like organisms and photosynthetic, plant-like organisms. Chemoautotrophs generally fall into several groups: methanogens, halophiles, sulfur reducers, nitrifiers, anammoxbacteria and thermoacidophiles.
Since these bacteria do not conflict with each other and they live in different ecosystems, thing should go on as they do now.

Answer 2

An educated guess here. They both utilize CO2. Photoautotrophs will have the upper hand if there are limited inorganic molecules for the chemoautotrophs. This is a hard question.

Answer 3

Photoautotrophs can produce glucose (power) with photosynthesis. Chemoautotrophs: besides to deriving power from chemical reactions, synthesize all mandatory organic and organic compounds from carbon dioxide. Chemoautotrophs use inorganic power factors, consisting of hydrogen sulfide, elemental sulfur, ferrous iron, molecular hydrogen, and ammonia. Chemoheterotrophs: at the instant can not restoration carbon and kind their own organic and organic compounds. Chemoheterotrophs might properly be chemolithoheterotrophs, applying inorganic power factors consisting of sulfur or chemoorganoheterotrophs, applying organic and organic power factors consisting of carbohydrates, lipids, and proteins
