A producer and multiple consumers

Answer 1

The usual composition of a food chain includes a producer and multiple consumers.

Producers (such as plants) convert sunlight into energy through photosynthesis, and then consumers (herbivores, carnivores, and omnivores) feed on these producers or other consumers. Decomposers also play a crucial role in breaking down dead organic matter, but they are typically not a part of the linear sequence of a food chain, which focuses primarily on direct feeding relationships.
