What is Chemosynthesis

Chemosynthesis is an alternative way to gather energy without the need for any sunlight. Bacteria cells often use this process by gathering in energy by taking in hydrogen sulfide, hydrogen or amonia. Here is the specific formula for respiration:

12H2S + 6CO2 → C6H12O6 (=carbohydrate) + 6H2O + 12S

Some orgnasms on don't depend on photosynthesis to survive due to some animals deeding off of proteobacteria that are producers creating energy with chemosynthesis.

Below are specific organisms in a food chain (first being the bottom and last being the top of the food chain) that depend on chemosynthesis.
