What role do bacteria play in the carbon cycle? apex
A. They break down dead organisms, which releases carbon dioxide.
B. They break down fossil fuels to use for energy
C. They absorb carbon dioxide in the process of photosynthesis
D. They fix carbon into forms that are usable by human

The carbon cycle is a biogeochemical cycle in which carbon is circulated among the biosphere, pedosphere, geosphere, and atmosphere of the Earth. The biotic and abiotic components play a crucial role in the carbon cycle.

The correct answer is:

Option A. They break down dead organisms, which release carbon dioxide.

The role of bacteria can be explained as:

1. Bacterial plays a crucial role in the decomposition of plant and animal bodies.

2. The bacteria replenish the amount of carbon, which is then used up by the plants to carry out photosynthesis.

Thus, the bacteria decompose the dead and decay material, which releases carbon back into the carbon cycle.
