Question

Actinobacteria sp. are fermenting organisms, which do not require oxygen to survive. These organisms break down organic material and convert it into inorganic material. Which part of the carbon cycle does this describe?

photosynthesis

respiration

decomposition

assimilation

Answer 1

The correct answer is OPTION 3: Decomposition.

• Decomposition, or rot, is the breakdown of dead organic matter into simpler organic and inorganic components such as carbon dioxide, water, simple sugars, and mineral salts.
• The procedure is part of the nutrient cycle and is necessary for recycling the finite matter that takes up physical space in the biosphere.
• When live organisms die, their bodies begin to decay.
• Worms, for example, aid in the decomposition of organic compounds. Decomposers are organisms that degrade.
• Even though no two species decompose in the same way, they all go through the same stages.
