Question

State the difference between the first trophic levels of detritus food chain and grazing food chain.

What do detritus food chains begin with?

Answer 1

The difference between the first trophic levels of the detritus food chain and the grazing food chain is:

• The detritus food chain begins with dead organic matter (decomposers).
• The grazing food chain begins with grasses (green plants, producers).

In short, detritus food chains start with dead organic matter, while grazing food chains start with living green plants (producers).
