What is the meaning of predator chain?

A predator chain, also known as a food chain, illustrates the hierarchical sequence of organisms in an ecosystem, showing who eats whom. It begins with primary producers (like plants) that convert sunlight into energy, followed by primary consumers (herbivores) that feed on these producers. Secondary consumers (carnivores) then prey on the primary consumers, and this pattern continues with higher-level predators. The chain highlights the flow of energy and nutrients through different trophic levels in an ecosystem.
