Detailed explanation-1: -A food chain is a series of events in which one organism eats another and obtains energy. A food web consists of many overlapping food chains.
Detailed explanation-2: -Food chain refers to the sequence of events in an ecosystem, where one organism eats another and then is eaten by another organism. It starts with the primary source like the sun or hydrothermal vents where producers make food, continues with consumers or animals who eat the food, and ends with the top predator.
Detailed explanation-3: -A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem. Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid.
Detailed explanation-4: -In ecology, a food chain is a series of organisms that eat one another (so that energy and nutrients flow from one to the next).
