Question
The availability of _________ affects decomposition.
- Non-sustainable development
- Sustainable development
- Sun
- Oxygen
Hint:
The term decomposition means “to break down”. It typically corresponds to the disintegration or rupture of complex organic matter into a simpler inorganic matter. It is one of the significant and essential processes of the ecosystem. Hence, decomposition is a metabolic process, taking up raw materials in the form of complex compounds, processing it and then converting it into simpler compounds.
Bacteria, fungi and a few other microorganisms initiate the process of decomposition and are known as decomposers. They feed on dead organisms to survive.
The correct answer is: Oxygen
The correct answer is OXYGEN
The oxygen present in the pores of the soil helps in the growth of microorganisms. In the water-logged soils, the aerobic microorganisms are absent. Here only anaerobic microorganisms can grow and initiate decomposition.
