Question

A food chain is made up of ____.

• A. biotic components
• B. abiotic components
• C. habitats
• D. ecosystems

Answer 1

The correct option is A biotic components

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. So a food chain is made up of many biotic components.
The natural surroundings in which an organism lives is called its habitat. The biotic (living) and abiotic (nonliving) factors in the surroundings and their mutual relationship together form the ecosystem.
