Rearrange the following sentences to form a coherent paragraph: 1. This mechanism, integral to ecological balance, ensures nutrient recycling within ecosystems. 2. Decomposers break down organic matter into simpler substances. 3. These substances enrich the soil, promoting plant growth. 4. Over time, accumulated biomass undergoes gradual decomposition.

4, 2, 3, 1
2, 3, 4, 1
1, 4, 2, 3
3, 2, 4, 1

Correct answer: 4, 2, 3, 1

Solution

Sentence 4 introduces the process of decomposition over time. Sentence 2 explains what decomposers do, sentence 3 gives the result of decomposition, and sentence 1 summarizes the mechanism and its ecological role. So the logical order is 4, 2, 3, 1.
