Multiple Choice

Which of the following best explains the role of decomposers in the cycling of nitrogen and carbon in organic chemistry reactions?

Decomposers synthesize complex organic molecules from simple inorganic substances.

Decomposers convert organic matter into inorganic compounds, releasing nitrogen and carbon back into the environment.

Decomposers store carbon and nitrogen in their biomass, preventing their release into the environment.

Decomposers fix atmospheric nitrogen into organic compounds, increasing soil fertility.

Verified step by step guidance

Understand the role of decomposers: Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter. They play a crucial role in recycling nutrients back into the ecosystem.

Identify the process of decomposition: Decomposers convert complex organic molecules into simpler inorganic compounds. This process releases essential elements like nitrogen and carbon back into the environment.

Consider the nitrogen cycle: Decomposers help in the nitrogen cycle by breaking down proteins and nucleic acids in dead organisms, releasing nitrogen in forms like ammonium or nitrate, which can be used by plants.

Consider the carbon cycle: Decomposers contribute to the carbon cycle by breaking down organic matter, releasing carbon dioxide into the atmosphere, which can be used by plants in photosynthesis.

Evaluate the options: The correct explanation of decomposers' role is that they convert organic matter into inorganic compounds, releasing nitrogen and carbon back into the environment, thus facilitating nutrient cycling.
