What is the main difference between Grazing Food Chain (GFC) and Detritus Food Chain (DFC)?

GFC starts with producers, while DFC starts with dead organic matter.

The correct answer is Option (1)- GFC starts with producers, while DFC starts with dead organic matter.

Explanation: The main difference between Grazing Food Chain (GFC) and Detritus Food Chain (DFC) lies in their starting points and the types of organisms involved.

GFC (Grazing Food Chain)

The Grazing Food Chain (GFC) starts with producers (typically plants) that are consumed by herbivores, which are then eaten by carnivores. While it represents one type of food chain, it doesn't encompass the interconnectedness of multiple food chains.

DFC (Detritus Food Chain)

The Detritus Food Chain (DFC) starts with dead organic matter, which is consumed by decomposers like bacteria and fungi, and then followed by detritivores. Similar to the GFC, it represents a specific type of food chain but not the complex network of multiple food chains.
