Question:
Biotic community that breaks down the complex organic compounds into dead matter is
Biotic community that breaks down the complex organic compounds into dead matter is
Show Hint
In an ecosystem, organisms are grouped by how they obtain food. Some make their own food, some eat others, and some decompose dead remains. The decomposers break down complex organic matter.

- Autotrophs

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
In an ecosystem, organisms are grouped by how they obtain food. Some make their own food, some eat others, and some decompose dead remains. The decomposers break down complex organic matter.
Step 1:
Autotrophs make their own food (for example green plants). Heterotrophs eat ready-made organic food. Aerophytes are plants that grow in air. None of these are primarily decomposers.
Step 2:
Saprotrophs (such as many fungi and bacteria) feed on dead and decaying matter, breaking down complex organic compounds into simpler substances. They are the decomposers described in the question.
Answer: Option (2) — Saprotrophs.
