A
An organism that preys on other animals
B
An organism that feeds on dead organic matter
C
An organism that decomposes organic material into simpler substances
D
An organism that produces its own food through photosynthesis
Verified step by step guidance1
Understand the role of a detritivore in an ecosystem. Detritivores are organisms that feed on dead organic matter, which includes decomposing plant and animal parts as well as feces.
Differentiate between detritivores and decomposers. While both are involved in breaking down organic material, decomposers (like bacteria and fungi) chemically break down organic matter into simpler substances, whereas detritivores physically consume and digest dead matter.
Consider the options provided: An organism that preys on other animals is a predator, not a detritivore. An organism that decomposes organic material into simpler substances is a decomposer, not a detritivore.
Evaluate the option: An organism that produces its own food through photosynthesis is a producer, typically plants and some bacteria, not a detritivore.
Select the option that correctly describes a detritivore: An organism that feeds on dead organic matter. This aligns with the definition and role of detritivores in ecosystems.
