<u>Answer</u>:

<em>Dead plants form the organic portion of the soil. </em>

<u>Explanation</u>:

<em>Plant bodies and animal bodies are rich in carbon compounds and when they die their body remains will contain these compounds.</em> Soil contains various microbes that act on the dead remains and break down the organic compounds within the remains.

The decomposition process releases <em>carbon, nitrogen, phosphorous etc that make up the organic compounds. </em>

Decomposition of plant bodies is termed as composting. Composting releases carbon in greater amounts into the soil. The <em>inorganic substances released after decomposition can be used by plants and other autotrophs for nutrition. </em>
