Question

The slow rate of decomposition of fallen logs in nature is due to their?

• A. Anaerobic environment around them
• B. Poor nitrogen content
• C. Low moisture content
• D. Low cellulose content

Answer 1

The correct option is C

Low moisture content

The correct option is C.

Explanation of the correct option:

1. A portion of the decomposition products are absorbed by the microorganisms, who also release simple substances after breaking down the complex compounds of the dead protoplasm of producers and consumers.
2. Because they contain little moisture, falling logs decompose slowly in nature.

Explanation of the incorrect options:
Option A:

1. In contrast to an aerobic environment, which is abundant in oxygen, an anaerobic environment is defined by the absence of free oxygen (O₂).
2. This type of atmosphere is devoid of oxygen, but it may include atomic oxygen bound in nitrite, sulfites, and nitrates.

Option B:

1. Decomposition is dependent on the rate of decomposition which includes (i) climatic factors and (ii) chemical composition.
2. Nitrogen doesn't affect the decomposition of fallen logs.

Option D:

1. Decomposition is dependent on the rate of decomposition which includes (i) climatic factors and (ii) chemical composition.
2. Cellulose doesn't affect the decomposition of fallen logs.
3. Fallen logs contain a lot of cellulose.

Final answer:
The slow rate of decomposition of fallen logs in nature is due to their low moisture content.
