The correct answer is first.

Key Points

The detritus food chain starts with the dead organic matter, which is then consumed by detritivores such as earthworms, snails, and bacteria.
The dead organic matter is also known as detritus, and it is the primary source of energy for the detritus food chain.
Since the dead organic matter is the initial source of energy, it is considered to be at the first trophic level.
The detritus food chain is important as it helps in the recycling of nutrients in the ecosystem.
